Smart Door Lock, Heavy Duty 5 in 1 Keyless Entry Door Lock, Full App

Was very easy and quick to install and has multiple ways to unlock including tags, fingerprints, passcodes and app. You do have to use the app to program everything but it is easy to use. The first one I had worked great for around 10 months until the actuator stopped working. It did die in the unlock setting and the backup physical key would still lock and unlock the door. Reached out to the company on a Saturday with issue and provided proof of purchase for warranty repair. I received the replacement on Wednesday which honestly was amazing. I had the new one set up and working within 10 minutes. I own 3 different programable locks and this has been the easiest to install, program and use out of all of them. Most likely will the replace the other with this one.

This lock is great. It has lots of features and everything works well. Installation was simple. A template for hole is provided for hole cutouts if you are installing it on a new door. I bought it for my bedroom door, and the main requirement was that it have a good fingerprint reader, so that I could get in quickly without needing a key or to punch in a code. The reader works very well and very fast, I'd say less than half a second to open. One thing I love about it is that the reader is angled at roughly a 45 degree angle, which makes putting a finger on it (I typically use my thumb) more comfortable than most fingerprint locks, which have vertical fingerprint readers. That may seem like a little thing, but it just feels like a more natural and ergonomic position. You can set up numerical codes (I think between 4 and 10 digits), and they can be permanent, one time use, or time-based. So, for example, you can set up a code that works from 4pm on Friday until noon on Sunday, so it's perfect for an AirBnB, houseguest, maid, etc. The code entry also worked flawlessly. Three keycards are included. You just put the keycard up against the keypad and the lock opens instantly. Honestly, I don't really foresee using them - as great as they work, I'll just use the fingerprint reader and avoid having to take anything out of my pocket. The backup keys provided in case of power failure (i.e., dead batteries) work fine. One minor nitpick is that the keyhole is hidden behind the face of the front handle, accessed by pushing on one end of the handle. It works fine, but my question is, will I remember 5 years from now (or whenever) how to access the keyhole? The TTLock app is really good too. That was a bit surprising to me, since a lot of apps for these kinds of things seem like afterthoughts. This one is intuitive and easy to use. If you have the gateway for the lock (purchased separately), it connects to the internet though your WiFi, and then you can even open the lock remotely. That's a feature I'm not planning to purchase, but I can see how it could come in handy for some people. There are a couple of features that I had not read about that I like. One is that the time that the door stays unlocked after being opened is very customizable (default is 5 seconds) through the app. Another is that you can set a daily period of time during which the door will stay unlocked, and then lock automatically. So, for example, you could leave it unlocked at night so that if the kids get scared, they can come in without them having to knock and you having to go open the door. The 4 AA batteries are easily installed. You need to remove one screw to access the batteries. A couple of minor niggles: I got the lock in aged bronze, which looks great, but the latch bolt and strike plate are both silver - would be nice if they were also aged bronze to match. Also, one thing I could do without is the voice saying "unlocked" when the door is unlocked and "locked" when it automatically locks again. You can control the volume of the voice by a setting in the app, but can't turn it off entirely. I think it's unnecessary, as there is a light that briefly turns green when the lock unlocks, and you can hear the it unlock and lock, so to me the voice confirmation isn't needed. But overall, this is as perfect an electronic lock as I've found. I can't vouch for its durability, since I've only recently installed it, but I'm very happy with this purchase, and I'm thinking about buying one for my garage.

This lock is great for the most part. The fingerprint reader works as expected. This is a big deal because some fingerprint readers don't work that well. You can also register multiple fingerprints with this lock. And, the app gives you more features like "passage mode" where the door remains unlocked during the hours you set, and "auto-lock after a set time". There is also a keypad that can be used and a hidden keyhole for the use of a key. In addition, I love that this lock can be used with a gateway ( sold separately), to lock and unlock the door remotely in case someone needs to be let in. What I don't like about it is that the motor is cheap and stops working in less than a year. However, customer service is great, and they seem to stand behind their products. They will send you a new lock if the motor fails. I also don't like that the key cannot be removed from the lock in the open position (maybe this was just a defect in the lock I received?) Overall, when you factor in their customer service, it is pretty good and feature-packed for the price paid.

This lock is cheap and the instructions make no sense. I never got it set up successfully afetre trying over the course of several weekends. By the time I gave up, the return window had expired. Do NOT waste your time with this product.

After my 24 hours of use, I am updating this post from 1 to 4 stars. It looks beautiful, n took 20 minutes to intall. VERY easy, perfect fit in standard US door. I even lost a screw & they give a spare bag so that's a nice touch! Spent an HOUR trying to get APP to work.. uggg.. "bad location" & "error failed", so be patient there. I learned the unit must be awake to communicate with door, except for APP lock & unlock. Subscription required to do things like add large numbers, remote use, etc at $65 for 2 years. Fingerprint is supper fast RFID a second or two, no bigs. APP gives you battery status, which is nice, but remote notifications requires a subscription. The ONY thing that's missing is an unlock mode where you can leave it unlocked for easy pass through without unlocking. Unloading groceries for example or in and out for a day... you can set a time, but no manual way to leave it open.. only via the APP. You CAN change pin codes after you add one they generate, use it once, then can change in the APP. The APP communication with the lock is sluggish but there's not much to do after it's setup, so not going to stress on that.

We bought this lock for our church office and it works exceptionally well. I was worried that the constant opening and closing of the door would hamper the locking mechanism but so far it has done really well. I love all the lock features and happy that there's a variety of ways to unlock. You also have to be careful to put your fingerprint right on the sensor or else you'll keep getting an error message, so it's very secure in my opinion. It works great!

Excellent lock with many advances features. This lock replaces our old keyed front door lock. Installation was very easy, the installation kit includes all needed hardware as well as clear instructions. The features this lock included is quite amazing, especially considering the price (about $100). The embedded features are quite amazing, especially the finger prints and NFC tags included. The smart app is very sophisticated and included features timed-access are very useful. The physical design of this lock seems robust and durable. I have examined other brand-named locks and for the investment, this lock system stands out as a great value. Definitely recommend.

The Harfo lock is decent -- I'm keeping mine -- but has a few problems. TL;DR: Pros: - Nice build quality, good looks, sturdy. - Installs easily, replacing standard door knob. - 5 different ways to unlock: fingerprint, passcodes via keypad, RF cards, via app, physical key. - App is really good and has a lot of features. - Power port in case batteries die. Cons: - Using the lock requires creating an account and registering the lock with Hangzhou Sciener Intelligent Control Technology Co., Ltd. (sciener.cn) - All data (fingerprints, door codes) is saved on Hangzhou Sciener's servers. - You must use the app to configure the lock. - Fingerprint reader is finicky. - Lock has an easily flipped "Privacy" button which could effectively locks you out unless you're an admin. Full Review: Pros: - Nice build quality, Easy installation: My previous smart lock worked ok, but it rattled and had a lot of play in it. This lock feels sturdy, there's no play in the door handle mechanism, and includes hardware that allows it to attach firmly to the door. Also, the look of the lock is understated -- not showy -- which I like. - 5 ways to unlock: Apart from fingerprints, you can unlock the door using one of the 3 RF cards provided, a keypad code, using the app or with a physical key. The key is meant to be used as a last resort, in the event the lock electronics fail. - Very good, feature-rich app: The app you use to control the lock comes with many features and is well designed. You can manage fingerprints, door codes and RF cards. For door passcodes alone, you can create permanent, timed, one-time, custom and scheduled passcodes. You can even send different types of eKeys. And, you can manage multiple locks and view access logs for each lock. There is a companion website which allows you to create an account and manage some of the lock's data, but you're restricted to editing and deleting entries. - Power port: There's a micro USB port under the lock's faceplate. It's to be used in the event that the batteries in your lock fail and the lock doesn't function. You can connect the lock to a powerbank and open your door. My previous lock had two metal contacts where you could jam a 9v battery. This is better. Cons: - Creating a lock account: In order to use the app to control and manage your lock, you must create an account and provide answers to security questions. I understand that not all data can be saved on the lock itself, but I didn't feel comfortable with all the data I was asked to provide. So, I provided fake answers to the security questions and made note of them. - Must use and login via app: You have to use the app to manage your lock, after logging into your account. I have a number of devices that are controlled via an app, including a sous vide cooker and the concern is always, what happens if the manufacturer stops updating the app and I can no longer use my app-controlled device? For a sous vide cooker, that's not a huge deal, but for a security device like a lock it's a slightly bigger deal. And, since you have to log into your account via the app, there's a second failure mode. The app could continue to work, but what if the website goes down? This to me was the biggest problem with the Harfo lock. - Finicky fingerprint reader: The fingerprint reader is finicky. This is true when adding fingerprints and when unlocking. For example, I wasn't able to add fingerprints from my wife's left hand, because, for some bizarre reason, her left fingers wouldn't register. Fingers on her right hand? No problem. Also, if your fingers are wet (rain, snow, sweat) there's a 90% chance the reader won't work. - Privacy switch: On the back of the lock (the "inside" side), there's a sliding switch labeled "Privacy". The idea is that when the lock is in privacy mode, only an admin passcode will unlock the door. I can see this being useful if you have a rental property that you sometimes use, and don't want someone coming in unexpectedly. The problem is that the switch slides over easily and is located where it could be slid into private mode by the brush of a hand. Unless you know the admin passcode, you could be locked out of your home. Luckily, you can turn off the privacy switch via the app, but you have to know about it first.

Little confusion around whether it is locked now or unlocked unless voice says so.. voice is good.
