Easy to installLooks goodWorks very seamlessly

It's not a thumbprint scanner it's just a touch button. Watch my review video for proof it literally opens with the back of my hand and the bottom of my foot.

My wife woke me up at 3 am this morning telling me that the door handle doesn't work, one of our kids is crying, and we're trapped in the bedroom. The door handle moved, but there was a strange friction and the latch wouldn't release. We searched the entire bedroom for a screwdriver to dismantle the handle, but there wasn't one. I video chatted with one of my daughters who found a screwdriver, but it wouldn't fit under the door jam. We tried nail clippers and scissors, but couldn't unscrew the handle screws. My wife started having a panic attack, dry heaving, while saying over and over again that we need to call the police to break down the door.My daughter was able to pass a screw head bit and pliers under the door. I unscrewed the handle, but it was the latch mechanism that was busted. A metal gear inside the latch mechanism popped out the top and wasn't moving the latch. I still wasn't able to unlatch the door. Grabbing the pliers, I pulled and twisted the cheap metal latch mechanism until I was able to pull it in the door socket and open the door. It was time for a pot of coffee and to start my day.TL;DR - The metal latch mechanism is cheap bendable garbage. Sleep next to a screwdriver and pliers.

I'll be honest, I was pretty ticked off when I realized this device isn't compatible with GeekSmart's Android application, but I suppose that's my fault for not reading thoroughly; I fully assumed that this device would have an app that accompanied it. Since this is the case, there's no way for me to remotely unlock the door for someone, nor can I ever update the firmware of this device...but, for the price, I cannot complain too much and as long as it works without hiccup (which so far it has), this should never be an issue in the future, either.With that out of the way, the build quality of this handle is absolutely phenomenal and it's extremely sturdy. I was not expecting the build quality to be so high and I'm definitely impressed. Once installed, there is not a single bit of "play" or wiggle to the doorknob and it's as solid as it can be. Seriously, not a single bit of movement and it's rock-solid!!Both the installation and configuration were very simple and it works flawlessly every single time I use it. I had every intention of knocking a star or two off of my review due to the lack of app support, BUT, I'm so impressed with the build quality of this door handle, it gets 5-stars all day long. Yet again, I'm very impressed and thanks a lot for an awesome product!! I cannot wait to roll on the floor laughing the next time my kids try to enter my office without my knowledge ;) lol

UPDATE: After just a few months of use, the fingerprint sensor has become a nuisance. Initially it worked very well and made me happy, but that changed quickly. I have to touch the sensor about 5 times for it to unlock. I added two of my fingers, and I experience the same problem with both of them.Old:Very nice, but I don't understand why the charging socket is on the outside. It would be more practical if it was on the interior.
