Smart Fingerprint Lock Biometric Portable Waterproof Padlock with Finger Print Control Safe Outdoor Security Touch Keyless Lock with Long Standby Time & USB Charging for Gym Office Cabinet Box - Black

I was hesitant to purchase this based on controversial reviews, but I am glad I decided to try.The lock stores up to 10 fingerprints, so theoretically (although I don't know why) you can set it up for up to 10 users.Of course it will not read your fingerprint when your hands are wet or after soaked in water for some time (swimming/shower/bath). However I have realistic expectations and no fingerprint readers that I have tried so far (the ones in the 24hrs gym, on my laptop or on cellphone) were able to overcome that problem as of now (2018).If your hands are dry, the lock opens up really fast. I have a friend whose fingerprints are so vague, she is unable to use them even for government purposes (and that is a real problem - poor her). I guess that people have fingerprints of different "clarity" (depending on how easy it is to read), mine are good in that respect and for me (and my hubbie too btw) the lock opens up right away in 99% of cases.I expect the lock to not open that good after "water procedures" like washing the dishes, I will update later on it.One cool thing about the lock is that you can place your finger at any angle and the software will still read the fingerprint. The software algorithm understands that the picture has to be rotated, which assumes a descent amount of built-in intelligence. Pretty impressing for such a small inexpensive guy.

It really worked great for 2 weeks then the battery went dead, no problem, I thought I didn't charge it enough (only opened and closed it 4 times).Recharged for a longer period of time after it was fully charged so i only opened it another 4 times and guess what BATTERY dead again! Not useful if it needs to be charged every 14 days.Is this defective or are they all like this???updated 10/21 outstanding customer support contacted and they indicated that this must have been a fluke and promptly said they would send me a me a new one.I will update when I test the new one .11/14, the replacement is still running strong on first charge no problems despite the temperature getting down to the teens at night . I can't remember how many times I've opened and closed it!Will continue to update.2/7/19, continues to open flawlessly on initial charge! despite temps in the single digits.It failed! 4/19 Recharge as I was having problems opening it.. customer support said that the fingerpad might be scratched or dirty so i cleaned and found no scratches or damage. it continued to take numerous attempts to get it to open I informed customer support again and they failed to respond.This lock is a nice idea but fails . I shouldn't need to purchase a new lock every 6 mo. it is not dependable. It would be nice to see a more robust fingerprint lock .I do not recommend this lock and will not purchase from them again.

This product was designed beautifully, but marketed to consumers before becoming reliably functional. I wanted it to work. It has a nice fit and finish, and is one of very few thumbprint locks available. It wanted to work. It beeped a lot- even in the box after it was deleted (hopefully) and packed for return- and it even worked a few times.Locks, however, are devices that need to be trustworthy. This product is a fail for now. I hope to see something like it that works well. Buyers- read the reviews on these. Look for over 4 stars. A malfunctioning lock is a bad thing. I had to cut mine off my gate with bolt cutters

Just horrible - never worked correctly and then within 24 hrs. it died completely when it was locked. Tried recharging but there is no sign of life in this thing. Fortunately, I didn't use it to lock anything until I trusted it and obviously, it never earned my trust.

It just does. Don't buy. It would recognize every fingerprint off my fingers and zero from my wife. The speed and responsiveness is not as claimed. I just went old school and got a good 2 set of 4 number locks for a fifth the price. I love tech but it's not here on this yet. At least not with this product. Junk.

This is not meant for outdoor use. The first one would not lock and the second replacement one would not unlock. Both worked for a little while then after a rain storm, they both malfunctioned.

After a rain and storm this lock stops working !!! Junk
