Review: Pretty easy to instal and has worked flawlessly for over a year. Good purchase.
Review: I bought two of these locks last summer and I've been using them since then and I've been very happy with them as they look super cool and worked just fine and I thought that they're well worth their price compared to other locks available. Since I only used the combinations that I set them up with to open them, I haven't realized until recently, that one of them actually opened with ANY combination. I set mine up with a 6 digit code, but then I had realized that any code, 4 digits or more, actually opened the lock, just the same and I had been living with an entry door that could've been opened with any combination by anyone, for almost a year. When I noticed this, I had started to use an additional mechanic lock to keep my door safe which kind of defeats the purpose of having the keyless digital lock in the first place. Since the return window on this lock had already closed, I contacted the seller about my issue. They sent me instructions on how to reset it, which I did and since then my lock works perfectly. The reset can be done only from the inside, so it's safe. I wish I had known this a while ago, but eventually the issue got fixed and I'm happy with my lock again. I still recommend it and still think that this is one of the coolest looking lock which well worth it's price.

### ⭐⭐⭐⭐⭐ Review
*by C***R on 7 March 2024*

This is exactly what I was looking for! I used this on the door into my garage. I wanted to keep my younger kids out since I had toxic liquids stored in there. I had a locked door set on, but it meant that if I locked it I would have to remember to bring the key every time I went into the garage and I am in and out of the garage many many times. This door lock is perfect since it automatically locks when I close the door and is easy to unlock using the key pad. I was a bit confused about the "anti-peek" feature but it just works. If I think someone is watching I just randomly enter a bunch of numbers and then in the middle of that random sequence, enter my real four digit code followed by some more random numbers. Once done, hit the # key and the thing unlocks! I love this. Way easier to install than some people have said and programming is a snap!
