Great, good quality, work well.
Really good. They are very picky about alignment / resistance - so need a little fettling on wooden doors that swell and shrink. Overall very impressed

quality, functionality, & app are all good
I took out a faulty Yale deadlock on my wooden apartment front door, and having checked the measurements carefully with the instructions (before ordering!), I found it very easy to install. It took a couple of hours, but mainly because my old door has had a couple of previous locks. I do have a lot of tools available, and in my case needed chisels, drill, screwdrivers & some filler .... but in a new door, this should be a dream to fit. I am really impressed with how it works, too. I don't need a separate control hub for this model, as it works through WiFi & is powered by battery. The eufy security app is *very good*, and this made the difference for me, against a similar offering from a very well known company (named above). So, I can open the door with codes, my fingerprints (as many fingers as I want to add) and I can allow others to do so too. I can set different levels of privilege, and use timed and temporary entry codes, all from my phone. I get an (optional) alert every time the door is opened or locked. I have ADHD, and eufy security gave me back my confidence - I set the door to lock automatically after a certain period of time, so I never forget to lock up! I can easily add a camera to my door lock - I haven't as it is an internal apartment door - but I do have a eufy outdoor camera, which stores videos locally on my phone. This means I don't need to pay for any storage subscriptions with my security system. All in all, I'm very happy with my eufy tech!

batteries lasted 6 weeks NOT 8 months as advertised. switch to lithium batteries
the locks themselves once set up work great but these are in remote apartments and needed t last a long time. The advert specifically states they last 8 months. mine lasted 4 weeks on 1 device and 6 on the other. very poor performance - about 10-15 locks/unlock cycles and the battery is dead. i deliberately placed a new wifi router next to the doors to guarantee a strong signal (5 feet away) so it cant be that. Update - I switched to lithium batteries after a chat with the support team. It took some time to get to the right person but once I did we got a fair compromise and this reflects in my review upgrade. the locks are now performing well. we run 2 air bnb apartments and having the ability to remote control is essential .

Best Smart Lock! And great customer service!
It has been a month or so since I purchased this lock. I wanted to test it for some time before writing a review. And now a month later, I can say definitively that this is the best smart lock in the market. It simply just works. Once I installed the lock, it paired with the eufy app seamlessly. The features I looked for where all found in this lock: 1. Lock must be smart (ie. connects to the wifi to allow me to control it remotely and get status if it’s locked or not at night). Being smart, it means I can generate one time codes to let people in remotely over the wifi. This convenience you wont have with a non-smart lock or Bluetooth connected locks. As those require you to be next to the lock to make modifications like add a new entry code or allow someone in. 2. Fingerprint entry. This is a game changer in terms of convenience. You want the fingerprint feature as it will save you a ton of time. You don’t have to manually enter digits one at a time. It’s a must have time saver. 3. Key pad. In case I want to let a guest in, they can enter using the keypad. I can generate a one time code ahead of time and send it to them via messaging. 4. Back up USB power port: In the rare case your batteries run out, this convenient power allows you to power the lock with a USB power bank and let you in the house. Then you can replace the batteries. 5. Battery powered: it uses 8xAA batteries, which seems a lot at first, but it means it will last long. It has been 1 month now and the lock is working very well. Using removable batteries makes this product more affordable, which is a huge plus. 6. It looks good! 7. Customer service has been really kind to me. The above 7 reasons make this lock an unbeatable lock. Yes, it doesn’t have a camera and it doesn’t have a door bell feature, but I already have a doorbell camera in my front door. I use this smart lock in my back door. A note on customer service: Customer service is very good. After I purchased the smart door lock and then after opening it, I realized that my door had an old style drive-in plate instead of the modern square plate. The instructions that came with the product said to contact customer service. My initial thought was that customer service would have a really difficult time to solve my problem. But to my surprised, they were very helpful. There was a little confusion in the beginning, but when they figured out what I was missing, they went above and beyond to help me locate the necessary part and then placed an order for me. This showed me that they really care. I have trust in the brand and the products and now recommend to friends and family! If you are having some doubts or haven’t quite decided on which smart lock you want to use in your home, this is that lock. Get it. You will love it. If you have money and need some more features like video camera, eufy’s got you. Trust me, just get it, you won’t regret. Enjoy the convenience of a modern smart lock for your home, family, and friends.

Great lock that makes life easier for everyone, including me.
Great price for a solid well designed product. I looked at a number of locks like this one, but none matched the features, price and quality I wanted. This is my first Eufy product and so far so good. High quality and a pretty easy install and setup. Make sure this will fit properly in your door. See the measurements provided by the company. The app is really pretty easy to use and I love the auto locking feature and the ability to temporarily assign a code to the person that takes care of our cats while we are away. It keeps a log of all the ins and outs and it also had alerts that let you know if the lock is being used. I need to take the time to fix the weather stripping our door so it closes completely, because sometimes the lock can't lock because the door is not fully closed. That is the fault of the door, not the lock and the cool thing is that the app tells me when it tries to automatically lock and failed. The only negative I have seen is that on a rare occassion, the lock seems to glitch when I go to lock it when leaving the house. I just wait a beat and then put my thumb on it again and it works great. The lock looks great and seems to be well built. We use it with Alexa as well and it was easy to integrate into the Alexa app. Fingerprint recognition is the same as what you do on the phone and it has never failed for any of us. We no longer have to worry about making keys or losing them, but it does come with a key in case there is an electical issue of some kind. I am really happy with this purchase from a price to quality and features perspective and highly recommend it.
