This Fingerprint, Bluetooth, Keyless, & Biometric Smart Lock is amazing right out of the box. First of all, is so well-made and appears to be very durable to last a long time. The functions and features really blew my mind and exceeded all my expectations as to their reliability, performance, and ease of use. Installing and setting up this Smart Door Lock is very easy and the instructions are easy to understand. The app that goes along with the lock is also easy to use and allows for so many great functions to make this the most complete and loaded smart lock I have used to date. The ability to create custom codes and one-time use is such a great function (especially for those that may get deliveries while away, or have someone coming by to care for their pets, babysitters, and so on) that the possibilities are endless. It also would make for a great Airbnb situation. The password random digit function is such a great deterrent and safety protection against people trying to watch you put in the code from being able to come back and duplicate what they saw you do. I really love this. The fact that there are 6 possible ways to utilize this lock (Fingerprint, through the app, using a standard mechanical key, passcodes, ID Cards, and remote when you purchase the Gateway device (that is not included) really impressed me. The other thing I like is that keeps a log of when the door was opened, how it was opened, and by whom. This Smart Lock is totally amazing and worth every penny. Best one I have ever seen

Great look, Easy Install
Appearance: I was so excited to receive this item and install it to finish up my game room look I was going for. I chose the gold look and upon review of the components, they were all good, no scratches or dents of any kind. The items felt good in the hand and not as if they were completely cheaply made. The handles had some weight to them. All in all I couldn’t wait for the install.Installation: I remembered there was a video of the installation of this product before I purchased it and that’s what I went off of. Made things super quick and simple and easy to follow. The one thing I’d recommend that should be mentioned in showed in the video is regarding the placement of the wired connection on the inner side as you connect the inner and outer pieces together. In the video it isn’t clear enough of how it’s placed and caused a minor hiccup in the installation as I had to find a place to put the connection to be able to push the inner piece to the mount to screw the outer piece in place. For me the rest of the process went smooth. I have 2 small concerned complaints: first is the door handles are tightened in place by a very small screw with a provided Allen wrench. We’ll see how well the screw holds up. Second: the cap covering the keyed access isn’t held on or tied on by anything so once the piece is removed it’s up to the user to put the piece back. In other words I feel it can be lost easily. In a way, it’s very easy to take them off and switch to other side if needed. After charging some batteries, installing the fully charged batteries, downloading the phone app (on iPhone 13 Pro), following the video to connect my locking device to the app was very simple and easy. I also tried the many other options (using keyed in codes on the keypad, fingerprints, included rf cards, and keys). Everything worked and went smooth. Tried the fingerprints the next day and all is well. This unit does speak (unlocked, locked, battery low, using keypad…and such). Not sure if this feature can be turned off but I like it so it stays on for me. Will update review if anything worthy to report.Overall Price: I feel the price may be a bit too high but according to other similar locking devices and the technology used, it’s acceptable.

Gold looks cheap, not as shown
Nice overall but gold color is not as shown, it looks like a shinier cheesy gold. Also fingerprint doesn’t recognize sometimes
