Perfect!
I love my lock. I use it all the time for the fitness center lockers. It’s small enough and lightweight that it’s no bulky or heavy in my gym bag. It’s so quick and easy to open with fingerprint and I’m on the way, not messing rolling dials trying to line up numbers or losing a small key. Definitely recommend.

Good Battery Life, works as expected, fingerpad needs to be dry
Had this for about 4 months now and use it daily. Once it’s set up it works as advertised. Sometimes you have to reset your finger 2-3 times to get it to open but it’s not a huge hassle. If your finger is wet it doesn’t work great and you have to dry your finger/thumb and the scan surface in order to get it to work. I am in SoCal so it rarely rains here. Battery life is impressive. Only charged it once in 4 months and it probably didn’t even really need that charge. I do wish there was a way for guests to use it like a key option as some other locks have but it hasn’t been an issue for us.

It works... until it doesn’t...
Update: as advertised in the product description it was for, I put the lock on my fence. I checked it a couple of weeks later, it was working fine. Now three weeks later, it won’t function. It won’t unlock, it won’t connect via Bluetooth, charging it does no good. There is no information anywhere for any kind of tech support. My recommendation now, look elsewhere. Lowering my rating from 4 to 1. At first glance the lock seems to be well made. I was disappointed though when the USB charging port port cover broke off the second time I opened it. So much for the 'water resistance'. I 'repaired it by using electrical tape to hold it in place. Hopefully that keeps it sealed because I bought this for outdoor use on a fence gate. But never a good indication when you're fixing a product with tape before you ever get to use it... That said, as far as functionality goes, I do like it. Programming the finger prints was pretty easy though a little slow. I got it figured out, then had my wife do it and she struggled but I was able to help her through it. The responsiveness to the fingerprint scan seems to open the lock pretty quick. The bluetooth connection takes a minute but it does connect. If not for the charging port cover, I'd be very happy. Hopefully the tape holds!

Great lock but only lasted 2 years
I loved how easy it was to use the lock. No need for keys or memorizing a combo. My fingers need to be dry so hopping out of the shower at the gym and trying to open was a small issue if I didn’t dry my hands well. The lock worked perfectly for 2 years then the motor that opens the lock stopped working.

Excellent lock.
It looks like the company who makes this (and many of the other identical locks) must have listened to the reviews by a couple of the locksmith/pickers on YouTube. They have fixed the issues with this lock that they pointed out. Of course, no lock is 100% secure, I don't care who makes it. A grinder with a cut-off wheel will open one every time. But as far as this lock being easily and quickly accesses that has been fixed. This lock is very secure. My hands get pretty beat up with what I do for a living so the finger print reader does not always work. When my finger is not chewed up, and rough, it works every time. The app is a little clunky but it is very secure with it's separate password. You also must use the app to connect it to a secure bluetooth connection. I have had this lock for a while now and it has yet to be picked, unlike some of the other I was using.

Easy to Install - Will Update in 6 Months
The lock was easy to install using the QR code which leads to the app, and from the app I was able to install my partner and I's fingerprint. It was intuitive enough that we didn't need to use the instructions to do so. The lock was already charged, I appreciate that, but the rubber seal over the charging part was a little hard to pop open (I used a knife edge to open it and it was fine). Works well opening it with our finer prints and the app. Well done. I will use this lock on my garage and will probably open it 1 to 3 times per week. I will update how well it works in November 2023, if there are any long term issues. If I don't do so, that means there are none. I have other things to do. To those that have trouble using the lock every day and/or with "wet" gym fingers. 1. Dry off your finger, air it out, blow air on it. Maybe they have towels. Try yelling at it. Sorry this isn't Star Trek and every new technology doesn't work perfectly in every possible scenario. A lot of things don't work when saturated: car, cigars, paper, your laptop, etc., etc. 2. If you use everyday, a lot, the battery will die faster. Surprise. Surprise.

REQUIRES APP AND ACCOUNT!!!
This lock is great for being a cheap but functional thumbprint lock. DO NOT think this will stop any sort of determined attacker! It just keeps honest people honest. So think like at the gym or pool or whatever. HOWEVER! It requires an app, account, and to be logged in to work. This really sucks, I understand needing the app for functionality but needing to be signed in is awful. Scary, and should be a non-starter for most people.

Worth the price
It’s working great even after 3 months. Fingerprint may not work if the finger is wet.

Not good
I bought two of these padlocks. One of them unlocks to any fingerprint and the other doesn’t connect at all! And the App once you register the lock on it, you really have to fight with it before it lets you see the product, you click on the product and it returns you back to select it again.

Stay clean and dry.
I’m writing this to pass on my experiences with this lock (I have 2 and buying 2 more) after reading other reviews. The fingerprint sensor does NOT work if there is water/moisture between your finger and the sensor. Also if your fingers have been exposed to water/moisture/hand lotion, your skin moves/changes/softens altering your fingerprint for a brief period ( time will vary from person to person for a few different reasons) until the skin has a chance to return to “normal “ as it was when you first setup the fingerprint(s) If you have damaged the skin on your finger and it left a scar/crease/fold it is likely to not recognize the finger immediately and more attempts with shifting your finger slightly may be required, and worse case scenario it won’t open at all. Always set up more than one fingerprint. It’s just common sense. Make sure your fingers are clean and dry , free from natural body oils, dust, pet hair, through static clinging, tape/glue residue , just to name a few contaminants. The battery life has never been a problem so far and I use one daily opening it 10x/day. You can also open the lock with your cellphone as a backup with the app downloaded to your phone. It works very well. I hope this helps for anyone who may be experiencing some difficulty when trying to open the lock. I have a different brand of fingerprint lock that works well but the size is smaller and I prefer and recommend this lock. Defects happen and new technology needs time to iron out any unforeseen issues by manufacturer so stay calm and chill when $h!+ happens. Solving the problem is much easier when you’re not upset or in a panic. I know. lol
