This is a relatively simple smart dead bolt that does exactly what you expect and the fact that there's an app is a great way to interface with the device. However, I had an issue in which the smart lock auto locked (which I did set) way too soon. I set it to 30 seconds and it locked after 2 seconds which meant that, many times, you didn't even have a chance to close the door before it relocked. This only happened when I used the mechanical (physical key or turned the knob) methods. Electronic methods to open the door obeyed the setting. I contacted the manufacturer and they were very communicative. After a bit of back and forth, they were able to create a firmware fix for the issue and it now does everything as I expected. I don't use all the features, but the ones I do use work reliably. The only improvement I can think of is I often have to touch the screen more than once for it to light up. Until it lights up, it won't accept your code, but this is a minor inconvenience since it takes fractions of a second to touch the screen again. If you can get over that very minor inconvenience and you make sure your firmware is updated (via the app), I don't think you'll be disappointed. It's worth the money and I really can't complain.

Cannot install on your own or make it work reliably. We tried to install it on our own and had a ton of problems - so had to pay $99 for installation from someone else. Then - it only works occasionally. We've been locked out a bunch of times because it keeps "losing connection to the gateway" or "bluetooth is out of range" when I'm standing right next to the door. DO NOT buy this product. Quality and reliability is terrible. Addition: I attempted to get a refund for this product and I can't... so BUYER BEWARE - Amazon doesn't stand behind their products and the manufacturer wouldn't refund me for a broken lock.

Nice lock, installation was pretty easy. Bluetooth nice extra. Open and locks perfectly. As with other reviews I did have have to change the R/L switch as instructions do not tell you from what side of the door makes it a right or left handle door. So I will tell you.... from the inside of your home with you facing the door, if your door handle is on your left then set the switch to the "L". You will not have to take it off and try again. Blue tooth was very easy to pair with your phone. Setting up codes was a breeze, except it does not let you pick your codes in the process. I finely figured out how to put your favorites codes.... instructions did not offer help on this problem... So here's how you do that..... set up a new passcode, then use that passcode to open the door. Then go back to the app and find that code in your passcode list. Tap on the passcode number and a option to change the code number will pop up. Then you can put in your favorite numbers. Only other con is the instructions are printed so small we had to use a magnifying glass to identify where and what screws we were suppose to use. I hope this information helps with your installation. Really good features are being able to set up limited times, permanent, or one time use for passcodes, being able to lock door off site, and to send a text with a code to let someone in.I highly recomend this lock and once you figure the app out, it is easy to use it !

Directions are in small print photos without written instructions. Template has no bottom hole which needs to be drilled for backplate screw to pass into. Can eliminate this by using a shorter screw. Beyon basic lock and unlock, programming instructions very poor, did not work in some cases, and need much more depth. Need to include a step by step pamphlet or on line tutorial. Need to call support (China business time) or email which makes it hard when need to program more immediately. Support is great when actually in touch. Bit of a language barrier though. Easy to use once programming is figured out.

I received this product last night 6/2/20. Instructions were straight forward. I installed in about 20 minutes. I did not drill the requested top hole because I live in an apartment but it’s still secure.In the box they give you everything you need for install. The door metal plates, all the screws needed for mounting. All you need in a Phillips screw driver. Followed the instructions with pictures. It tells you step by step how to install. Very easy.The TTLock app that you use with it is great. It works via Bluetooth. To control or add passcodes you must be with in a few feet of the door. I have ordered the gateway to allow remote control so I don’t have to be anywhere near to control.This lock is great and simple to use. Price is great and the mounting is awesome. They have rubber in between the front part and door and also the back lock part.6-7-20- I purchased the gateway to allow remote entry from my phone over WiFi. Best thing I did. Without it I would have to be about a few feet from the door to use Bluetooth and I didn’t want to have to send keys via app just for quick unlock and lock.
