smart purchase
The smart lock has been one of the best decisions I've made to improve my home security. Installation was quite simple, even with no prior experience with locks. The instructions were clear.The mobile app works perfectly: I can open and close the door from my phone, assign temporary codes to family members or guests, and receive notifications every time someone enters or leaves.The design is modern and discreet, and of good quality.This lock combines technology, design, and security. A smart investment for any modern home!

Year review
Love my smart door knob. Very reasonable price and had it for over a year just now doing a review. Works great.

Do not buy this lock!!!
I NEVER leave reviews but this product is spectacularly terrible, I felt obligated. I installed it today and already have a problem. I didnt even make it a month or weeks but day 1! Lets start with the install. Installing it is relatively easy. Insert latch, attach outside knob, attach inside knob, connect wires, install batteries, boom! Ill give it that. But there WAS a problem. I installed this on a standard US door thickness that goes to my office. The 2 black screws that come with this that hold the two knobs together thru the latch ARE TOO LONG!!! So the knob was loose and not snug against the door on either side. Bcuz they literally couldnt screw in far enough. It felt terrible and cheap like it was going to fall off. Which then led me down an adventure of trying to cut the screws but I bent them while doing so so I had to replace them with other knob screws I happened to have around the house. But the two holes on this knob are smaller than standard. So I luckily happened to have some that fit right for it...kinda. Well I had to make em' fit but they fit i guess. So now that the knob is installed, guess who got locked out of their room today. That's right. ME! I programmed and tested the fingerprint reader a thousand times. Opening and closing the door throughout the day making sure it worked. Later tonight, not long before I wrote this review I had an emergency and had to leave. I didnt think about the door or grabbing the backup keys bcuz again used it all day. And you know emergency and all that. Well when I came back, guess what didnt want to let me in. Now to be fair, it recognized my fingerprint and I could hit unlock from the app but every time I went to turn the knob, it did not open. I almost took a saw to it but miraculously after my 100th attempt on it right b4 I cut it open, it opened. Suffice to say, it is now off but I may be past the return period as I bought this a while ago to install it on my office door in my new house that I knew I was going to be moving into. So I will be getting another brand but wanted to share my awful experience with this lock. Also third but not least, the app is very basic. I have an ultraloq on my bedroom door and front door and they can do almost anything you need a smart knob to do from the app. The only reason I didnt get one now is because I wanted to try something different. And now I know why ppl stick with what they know. Also the bluetooth keeps disconnecting so if I need to open it real quick if I have a visitor, I have to open the app, connect via BT which it may not even connect to bcuz im across the room and the BT doesnt reach. I'm not mad, just disappointed.

Highly recommended
It took me 30 minutes to install 2 of these locks and I don't consider myself handy at all, so if you know how to operate a screwdriver you should be able to do it too without any hassle.What you will need are actually 2 different Philips screwdrivers: one with the regular head size and one smaller, as well as 4 pcs. of AAA batteries.There was also no issue at all in adding both locks to the GoSund app. It took me a moment to find the Settings section in the app on Android because you simply need to scroll down the screen to see the other tabs in the menu, which are hidden by some other stuff.The locks operate as expected and the fingerprint reader is quite reliable. From my experience you need to press it for about a second, so don't remove your finger immediately, because it may not be able to read it.I also connected both locks to GoSund Mini BLE Gateway, which makes it possible to operate the locks via WiFi from anywhere in the world, so you can unlock the door for somebody who doesn't have a key set, or just check the logs of who was getting in and out and at what time. Nice!What I also like about this lock is that you don't need to dismantle it completely to change the batteries as it's enough just to remove a single screw and put the batteries inside, which anybody can do in 30 seconds.In conclusion, based on my initial experience I can recommend this device if you like to have smart functionality for your doors.What I would put on my wishlist for the manufacturer are the following:- better marking of the "+" and "-" for the battery chambers, maybe with some white stickers, so they would be easier to see,- NFC functionality, a mobile phone would become your key, and the lock would recognize you when you are nearby and unlock the door without the need to even touch it, which could be a big advantage if you carry some stuff, or if the weather requires you to wear gloves.
