Bought this lock for gym use, love the idea of no keys needed. Had a few issues with it but the seller reached out and made it right. Cool little device.

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.

Let me start by saying this product was exactly what I was looking for and at first it worked as expected, but ultimately it failed me in a big way. I use a padlock almost everyday, when I go to my gym. I am getting older so seeing the dials on a combination padlock became a problem. I started using a keyed lock instead, but hated having to carry the key around with me. This fingerprint padlock seemed to be the answer; and it was, for a while. I started to notice that after my workout, after my shower, the sensor wouldn't always pick up my fingerprint. If I waited a little while, and dried off my fingers and the lock, it would eventually recognize the pattern and open the lock. The first time it happened it worried me but I got used to that was how it worked. (Incidentally, I had coded multiple fingers/fingerprints onto the lock, just to be safe, and none would be recognized when this happened.) I checked the battery on the lock, to make sure it was not running down, and it showed the charge was over 90%, even after a month and a half in service, which I thought was awesome. Last night, however, after my workout, the lock wouldn't open, and the sensor indicator lights stopped lighting up. I tried all of my tricks and nothing worked, the lock would not respond. Adding to the problem, I had worked out late and my club was closing. I waited about 5 minutes, trying the lock, unsuccessfully, on and off. Finally, I was forced to walk through the club with a towel wrapped around me, to go to the front desk, to get something I could cut the lock off with. This was 5 minutes before closing. I had to cut the lock so that I could get into my locker, where all of my clothes, wallet, mobile phone, and car keys were. You see the problem. The lock is now ruined and useless. When I got home I tried the sensor again, and it worked fine, i.e., it recognized my fingerprint and the lights indicted the lock would have unlatched, had it not been broken off. The perfect solution for such a technology would be to have a backup/override solution for if/when the biometric/fingerprint functionality doesn't work. Perhaps a combination override that could be used instead. That would provide the convenience of being able to use the fingerprint technology most of the time, with the peace of mind of having another way to open the lock should the fingerprint technology fail. It is a very helpless feeling when the lock you depend on fails and you have no other option then to destroy it to get to the stuff it was supposed to protect. Ultimately I cannot recommend this product. I found that it just couldn't be trusted.

I ordered this Lock a few months ago. I wear glasses and it’s hard to see you when I get out of the gym. So my fingerprint lock was the solution. It has been working wonderful. Last week I came out of my workout and noticed that the lock was unlocked. I guess when the battery dies it automatic unlocks. Which is helpful. When I went to charge it, it would not charge. I tried again and again. Nothing worked. Finally, I ordered this replacement. When I got the replacement in, it comes with its own charging cable. I use that cable and my old lock started to charge. So be warned. It only Will allow its own cable to charge it. So don’t lose it.

I love this lock and their customer service and responsiveness is TOP NOTCH! I purchased this fingerprint lock a year ago for work. It was easy to download the app and set up and works so well for me. I don't have to fumble with a combination and can quickly access my belongings without a hassle. At some point, I misplaced the charging cord and could not seem to get a charge using the compatible cords I had at home. **I HAVE HAD THIS LOCK FOR ONE YEAR** Not only did it still have a charge (8%) after consistent use, but when I contacted customer service one year after purchase, they gladly sent me a new charging cord free of charge. They remained in contact with me via email until my cord was received and my lock was functional again. Excellent product. Excellent customer service.

One of my favorite upgrades. So much better than a combination or key lock. Battery lasts forever. You can program multiple fingers. Every once in a while will take a few attempts to validate the fingerprint but overall great purchase.
