  • Very good.... especially for the price!
Color: Matte Black
I bought 2 of these. They work very well, unlock /lock action is quick. It programs easily with the app, you just have to be very close to the unit. It comes with a couple of programmable cards that work well as you can simplify put inside your phone case, or in my case, behind my car key fob, and simply touch the card to the screen to lock/unlock. Easy to link Alexa to the app as well. You will need a hub, however, if you want to remotely use the lock. It's important to install these correctly and test the ease of the locking bolt, because if it strikes anything or encounters too much resistance, it will not operate correctly. Overall, this is an outstanding value, one of the least expensive smart locks, but packed with features and built well. I waited a couple of weeks to review, so I could make sure it still works great after a bunch of use, and they do! ... show more

  • Great features for a great price. Watch the videos first
Color: Matte Black
I just installed the lock and started the review, super easy installation since I already had an existing deadbolt. The feature the sold me was that is has an old school key to get in if the electronics fail. MAKE SURE it watch the identify the left right door video it will save you a lot of trouble in getting the lock setup correctly (let’s just say that I would have saved myself lot of frustration, guys who needs instructions right lol). It is set it in the MORE/SPECIAL FUNCTION. Works great very easy to use the Tuya App is very user friendly with setting up the various lock/unlock features. Connections via the app is easy. So far so good after testing the various features I think the value of this lock is well worth the price. Let’s see how it goes after a few months. ... show more

  • total garbage
Color: Matte Black
This is an absolute piece of crap. You have to download an app that fails to link to features like the fingerprint option. There is no manual set up through the lock itself so the functionality of the lock isn't even available through this poorly designed app. OH but it get's better. I went to test the code that I was able to set only to find that when I unlock the door it says, "locked" and then a few seconds later unlocks the door and says, "locked". So I can't lock the door and now when I'm hoping to go to bed, I instead have to remove this lock and put my old deadbolt back together. Unf'ing believable. ... show more

  • Looks nice! Easy to install
Color: Matte Black
Looks nice. Seemed easy enough to install, my husband installed it and it seemed to be installed quickly. I bought this lock because I’d bought a different style lock (a doorknob lock) that uses the same app, and i like that lock. I don’t know if my door is weird but it doesn’t always unlock? I’ll put my finger print and it will say unlock but won’t actually unlock so I’ll have to redo it, it doesn’t do it all the time, but when it does it’s sort of annoying. But it could be my back door, itself? Because before installing this lock I had a regular dead bolt lock and sometimes it would stick or not lock properly. So it could be my door? ... show more

  • Easy setup and easy-to-use app.
Color: Matte Black
Bought this to put on an interior door in our house. I did have to modify the latch hole to make it deeper so the deadbolt would fit (if you use this on an interior door you'll have to do the same). Installation was easy and there are several ways to lock and unlock the door; physical key (of which there are 2), the app, fingerprint, or pass code (Can have one for each family member if you so choose). A great buy for keeping young kids out of areas you don't want them in, but in general it's a great bit of added security for your home. ... show more

  • Will definitely buy again
We purchased our new home and immediately wanted to change the locks. This keyless entry door lock allows us to type in a code, unlock from an app on our phone, unlock with a finger scan and has a key option just in case. We really like that the numbers are not always on display and do not get the worn marks like the buttoned key pads do. There is a door bell on the key pad as well and is quite loud for such a small item. We would definitely recommend this for your home! ... show more

I love it the instructions suck but I was still able to figure it out after playing around with it I already had the app because some other devices use it it programmed very easily and works great and if the door doesn't shut all the way it will tell you lol good buy for the price just get one
