Fantastic Purchase - Made a huge difference
I'll start by saying I never leave reviews, but sometimes you buy something and just have to... 1 - Setup Setup was a breeze, download the app, grab one of the units that you'll use as the main device and select which mode you want to use (I opted to completely replace my router and use the 'main' halo as the router). You're guided through the process and are asked if you want automatic or manual setup. I first tried manual which I'll be honest I couldn't get to work, when selecting automatic I waited about 10 minutes and boom first halo up and running. Get any additional units, place them strategically and again use the guided process to link each unit together. All up and running in about 30 mins. 2 - The app I actually don't quite understand some of the poor reviews stating the app being a limitation. Yes, you can't quite do EVERYTHING you could if you had a web portal like some of the more expensive units. I work in technology (and have worked specifically in a networking capacity) and I honestly couldn't tell you what 99% of users would need that the app doesn't offer. Port forwarding / QoS / priority etc etc can all be done via the app. It also notifies you of any new connections, allows you to name and categorise the devices (great for younguns whom you may want to restrict certain websites from). And you're able to setup 'profiles' for each person so that those profiles are applied to the devices they add. At first, my main PC was dropping (very occasionally), go into the app, select the device and then bind it to the strongest unit (rather than using the roaming capabilitis) and its been absolutely rock solid ever since. Also, the 'network optimisation' function is great too, I've only used it once but it found a really good channel (verified via inSSIDer) and I'm on a quiet channel with little interferance. 3 - Stability / Speed I've had this now for about 8 weeks and I've not had a single problem with it. I've seen in some other reviews they've had to reboot a unit or 2 etc but (whilst I know its early days) I literally haven't had to touch it since setup. Its been absolutely fantastic from the day I installed it. I'm an avid gamer and with my previous setup I'd have the odd disconnect (only breifly) and some games just don't deal with that well. One of my favourite games did this and I'd have to log out/back in again multiple times per night (not good with the type of game played). This setup has COMPLETELY illimintated that and has also reduced my average ping by about 12 (now sitting at 7ms ping on almost all games). Speed wise, from the further point in the house I can get from any of the units, I lose about 10% and no more. My provider gives me 300up/300down and again at the furthest point I get 275/260. 4 - Conclusion For the price paid for these units (I got the pack of 2), at the price of purchase £59.99 they're probably one of the best networking kit I've purchased. Replacing a £300 'WiFi 6' router, these absolutely smoke it out of the park. PC's/Laptops/Phones/Gaming/Downloads have all performed significantly better on these than the previous, much more expensive router I honestly wished I'd tried these much sooner. Finally, downloading/streaming etc on multiple devices all at once this kit doesn't miss a beat. Previously if we had guests round all doing their own thing we'd see some speed drops and inconsistencies. With this, everything I've thrown at it so far no matter what you're doing it just handles it, no questions asked. If you're on the fence about mesh, or even considering a new router I'd honestly suggest giving these a try. They're owned / operated by TP-Link as their 'consumer' focused brand, but honestly they outperform everything I've tried so far (AP points/extenders/very expensive routers) and I'd have no problem purchasing Mercusys again. Fantastic piece of kit and I'd buy it again no question.

Easy to set up, work well, good app.
I've got five of these in total - a three pack and a two pack. Running on a Virgin Media Router, 1gb connection. They provide good mesh coverage and the app is easy to use and understand. Plugging in an ethernet cable provides high speed - no idea how it works (as it's coming via wifi and then through an ethernet) but it does, and my "gaming son" is very pleased with the speed. Look nice enough when out on display, and all seem to connect each other well. I'd recommend these.

You get more than what you pay for.
Ive spent 2 days setting this up. On day 1 I set up a Halo network based on the sequence of operations on the App, which worked fine but it wanted to work as a router. This was ok but my existing router network uses around 18 smart devices including bulbs, switches, thermostats, Alexas Roku devices and printers. I decided to use a separate Halo network name and SSID and password. It seems that these all need to be accessible around the house, and so I could either switch them individually to my Halo network or change the network to use the existing router as an access point. and set the Halo Network to the same SSID and password as my routers Network. The idea being that The router would handle IP addressing, and the Smart devices should just appear on the Halo network. On Day 2, I changed the Halo net name to my Routers SSID and Password. (easy) Then set the Halo net to work as an Access point (also easy - via the Mercury's App). Then optimised the network - again on the app. There was some conflict going on between the router Wifi and the Halo Wifi so I turned off the Router Wifi. Now I have 12 devices showing as online on the app. the other 6 devices show as offline. 2 are actually offline but 4 are not - These 4 are smart switches , and fortunately they work fine via both the smart life App and via Alexa. It's just that they show as offline on the Halo network. Not sure why . FAQ and the online manual don't help with this issue. I guess I need to try out their Tech support. Another issue is that my wifi printer is too old (10 years - Epson BX525WD) to connect to the Halo Network - :^((. It keeps showing Network connect fail incompatible wifi. So Im quite happy with the system. I could use a couple more Halo units to cover our conservatory and hopefully the garage, but will get used to the current system first. Pros: easy to setup. Works well once configured correctly. The Phone App is really good. Cons: range less than expected. Detailed configuration is complex. Interaction with existing wifi has conflicts. My biggest ask: It would help to have a setup manual or at least FAQs for how to apply to a smart device network. Pics : 1 - Connecting the main halo to a router. 2- The halo running after closing down the router wifi. 3- Main halo with some clients inc Smart Thermostat. Update after 1 month Use: 1. Upgraded 3 to 4 stars 2. Very reliable wifi at a min speed so far of 300 mbs (the more clients the lower the speed) 3. Printer working in the mesh by connecting it to a Halo in my upstairs office - working really quickly. 4. IoT smart switches seem to show as online if they are in a line of sight from a hub rather than behind objects. In the main they still work even if showing offline in the app. 5. Now planning to extend the mesh with a couple extra Halos

Transformed my wifi performance!!
I had Fast Fibre installed and was given a new Eero 6 Router by TalkTalk. I have an older property with thick interior walls and with the basic one Eero I only got my 150 Mb/s in the room the modem was located. Elsewhere in the house Wifi was very poor and unstable, reducing to 1-5 Mb/s in the next room! I looked up the cost of expanding the Eero 6 Mesh system and found the cheapest 3 Eero 6 pack was around 300 pounds! Instead I opted to continue to use the Talktalk wifi hub/router (which can cope with 150 Mb/s) and look for a cheaper Mesh system. Having ploughed through dozens of adverts I found the Mercusys system. I know the Talktalk Wifi Router and the Mercusys are Wifi 5 rather than Wifi 6 but, as I said, this set up can cope with and produce Fast Fibre speeds of 150 Mb/s which is more than enough for me. Having bought the Mercusys system, set up was really easy using the Android app you can download. You do need (at least I did) to create a new wifi network ID but this was very easy. I basically have the main Mercusys unit plugged into my Talktalk Wifi router/hub and you then set up each additional Mercusys unit by connecting it to the main unit using the app. Although this might all sound complicated believe me it is not. I had the whole Mesh system running in15-20 minutes. The improvement in wifi performance in my home has been outstanding. I have the main Mesh unit in my front room. I placed one Mesh unit on the same floor in my main living room and the third on the upstairs landing. I have now got 150 Mb/s throughout the majority of the ground floor and first floor. I have five bedrooms and four reception rooms and even at the furthest point, through several thick walls I get 50/60 Mb/s. I could also expand the system further if needed very easily. I have had 9/10 devices using the Mesh network simultaneously with no performance loss. This is, without doubt, the best £80 I have ever spent on enhancing my wifi - thoroughly recommended.

Good Wi-Fi coverage at last
Having switched broadband providers, I found myself struggling to get Wi-Fi in all the rooms of the house. I nearly ordered a pod from the provider which would have cost £8 per month and would have to be returned at the end of the contract, but couldn’t get their system to order one. So, I decided to get my own solution. I starter by trying cheaper range extenders, which I couldn’t get to work. Then I stumbled on a report on mesh Wi-Fi systems, which it said were easier to install and better. The article was not wrong. This system comes with an app which provides literally step by step instructions. One of the three hubs is attached to the router and the other two plug in at different places in the house. It creates a new Wi-Fi system over the whole house and it was so easy to install. No more dead zones, strong signal everywhere and the extra cost is well worth it considering I would have been paying out every month for the internet provider pods and would never have owned them. Even if I switch again, I can simply plug the mesh system into the new router. I love these things!

Very good, decent app, not without faults.
Had these for a few months now and the experience overall has been very good. Coverage is excellent throughout the house and outside, which is a standard three-bedroom, ex-council property with 10m rear garden. Our set up is with two wired 'halos', one at the front of the house, another at the back and one running off WiFi in the middle. Speed is also very good in having no issues streaming video from various to phones or tablet, albeit at only 1080p. Though, sometimes the TV does lag a little bit and takes a while to run in 1080p, and I suspect this is connected to the halo which is not wired since that is the closest. Set up was pretty straightforward and app does a decent job of walking though the process, based on the premise that you are only connecting one halo by wire. It does not jump out at you if you're looking to connect multiple halos by cable... Which resulted in me creating a network loop and causing internet issues as I had connected two to the router, rather than daisy chaining them. The app does explain this, but you have to go searching for this information rather than it being presented to you during setup. Since then I've only had minor hiccups, where every other week or so, the internet will slow down considerably, and using the 'optimise network' function in the app will clear this up straight away. The management side of things in the app is nice, and having the ability to control the WiFi whilst I am not at home is a bonus. For those who finds this dials back to China, it is because the management of the network is cloud-based, with the cloud servers operating in china

Do what they are meant to do
Work fine and do what they are meant to do but speed does drop off at the time you get to the area the last one covers, easy to set up and app is fairly good, price is slightly on the expensive side though

Slower than a slow thing in a slow situation!!!!
Mercusys H50 Mesh system was very easy to setup although the power cables for the individual 'mesh' units are far too short for any normal situation. So unless you are placing the units next to a power socket you will need to purchase extensions for the power. This is setup in a three bedroom house (fibre with cabled speed from the router of approx 950Mbps) with the main unit downstairs in an office, the first remote unit next door in the living room and the third unit setup upstairs in a bedroom. So Wi-Fi switched off on the fibre router, main mesh unit connected directly by ethernet cable to the fibre router and the two remote units both connected by Wi-Fi to the main unit, the Mercusys app telling me that everything is OK and showing both remote units connected to the main unit. Ethernet cable from main unit to router is Cat7. First thing is that the speed is very slow - using the Wi-Fi directly from the router (i.e. before the Mercusys Mesh was setup) I got around 900Mbps downstairs with 600Mbps upstairs, anywhere in the house. Using the Mercusys H50 Mesh and standing next to the main unit in the office the maximum speed I have seen is approx 350Mbps and upstairs it drops to around 100mbps. The other thing that is concerning, is that with a 'mesh' you should connect to the nearest unit as you move through the house with the mesh maintaining the strongest signal - unfortunately my devices rarely connect to anything other than the main unit, i.e. if I am upstairs standing next to a remote unit, my phone still shows as connected to the main unit downstairs and using the Mercusys app to show the mesh status confirms this and very rarely shows anything connected to the remote units. It does occasionally connect to the remote units but there is absolutely no change in Wi-Fi speed. Then approximately once a week, the speed will drop to under 50mbps at the main unit, which rebooting from the app does nothing and requires the mains power to be switched off at the main unit before the speed comes back up to its low 300mbps. This system is advertised at having 'speeds of up to 1,900 Mbps' so should at least come close - down to 300Mbps from over 900Mbps from a fast fibre installation is unacceptable!
