  • Good Battery Life, works as expected, fingerpad needs to be dry
Color: Gray
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. ... show more

  • Fail
Color: Gray
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. ... show more

  • Easy to Install - Will Update in 6 Months
Color: Blue
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. ... show more

  • great concept...great customer service
Color: Blue
Bought this in January 2023. i chose it as with increasing age came the need for readers to be able to read text and numbers including combination locks. not convenient when at the gym and not using readers. so i stumbled across this fingerprint or App driven lock. set up is very easy. once you fully charge the lock it took 5 minutes to set up both the fingerprint unlocking mechanism and downloading the app and connecting the lock to the app via bluetooth. once set up you can lock or unlock it either way. within the app you have the ability to set up multiple fingerprints to be able to use the lock. also it shows you the battery strength. was really happy. then 9 months later in October 2023 it stopped working. nothing worked. fingerprint didn't work it was no longer linked to the app which was on my phone. went on line to the manufacture website and went through all the troubleshooting hints. nothing worked. couldn't even get it to accept any charging via the USB connection (which is the only charging method). so on the website i reached out to customer service. after couple back and forth emails , with me proving i bought it on amazon they agreed to send me another one even though officially outside there refund window. just got the replacement and intend on sending the broke one back for quality control. so far so good with the new replacement lock. everything mentioned above applied to the replacement lock. will update further if warranted. ... show more

  • Lasted for almost a year on the first charge.
Color: Blue
Had this for about 10 months. Worked fine and then just stopped the other day and wont charge. Found out that the charging cable is a bit different from my regular usb-c. Charging well now.

  • Issues after 6 months
Color: Gray
I bought three of these locks - all eventually stopped opening - although battery says there is power. When charged to 100 percent it works only for a short while and fails before 90 percent is reached so its not a battery issue but a software or connectivity issue.
