Bluetooth padlock

The lock stopped working about an hour after I first used it, losing the ability to program an administrator fingerprint. The lock was intended as a gift for a friend. I had tested programming it twice with my fingerprint. When I cleared the memory for the second time and went to help him program his own fingerprint, that's when the lock stopped working. There's a "setup" button which, when pressed, is supposed to put turn the status light blue and put the lock into fingerprint-learning mode. The status light no longer turns blue, and the lock no longer appears able to learn a fingerprint.Obviously, I don't recommend this product, but if you decide to try your luck anyway, realize that even when the lock works, the fingerprint recognition is very finicky compared to the iPhone 6. There's no causal touch-and-unlock experience like you get with the iPhone. You have to put your finger just so, applying just the right amount of pressure, and swipe it down at just the right speed. A full 8-1/2 x 11 page is devoted to the swipe technique you need to use.The instructions that come with the product are written in the type of mangled English that you still sometimes see in Chinese-made products. It's surprising to see them in a "high-tech" product that costs a hundred dollars.

**** Update 1/29/2015 ****Six months of use have convinced me this is a good product. Innovative devices like this are often shabby; not much more than prototypes. I was very surprised I hadn't had to replace the batteries I originally put in, too.I had a malfunction with the unit. A tiny nut came loose and the electronics were no longer working reliably. I contacted the vendor and they were happy to give me a replacement. I transferred the same batteries to the new one and in a few minutes had it trained on three of my fingers. Good to go again.Note that vandals could easily steal the batteries; there's no special protection for the compartment. Also, they could run dry out at any point. So I keep an extra pair in my car, along with the electronic master key. And I keep my car key in my pocket instead of in the locker. I'd rather not have a bolt cutter be the only way I recover my lock and items. Think about your fallback plan. I was lucky my malfunction happened when it was not on a locker.This lock still deserves five stars for being a good and innovative product.**** From 7/4/2014 ****This has "wow" factor. It's a great geek toy. But honestly, this is actually practical to me, too. I work out at the YMCA several times a week. I don't want to carry a key or remember a combination for a typical padlock. It is fairly big, to be sure, but it just barely fits the Y's lockers. And all I have to do is tap a button and swipe my thumb on the sensor to open it, a one-handed operation. You don't need to do anything to lock it except close it like any other padlock. Note that my sweaty, dirty hands don't seem to confuse the sensor after a workout.The complex feature set means you need to learn how to use it. Read about setup before you try it because you'll be needlessly frustrated if you don't. Here's my own summary.With a small phillips screwdriver, open the panel on the bottom. There is a USB key fob that plugs in here. This is an emergency unlock key, an awesome feature. I keep mine in my car and keep my car key on me in case there's ever a problem with the sensor. Just plug it in and it unlocks.The key fob is also a master reset. Once plugged in, press the tiny "learn" button next to it. All fingerprints are cleared. The first one to be learned will be the "admin" user.Here's the part that confuses a lot of people. Each time you want to add another fingerprint -- I'd recommend you do at least two of your own fingers, BTW -- you need to tap the "learn" button and then "log in" using the admin fingerprint. You don't need (or want) the key fob for this part. But logically, you would not want just anyone with a phillips screwdriver to be able to add his/her own fingerprint, right? That's why there is an admin login first.Learning a new fingerprint can be a bit confusing and quirky. Read the instructions for the exact sequence of button presses, LED colors, and beeps. The main point is that you want to swipe several times, pressing fairly lightly (mashing the sensor makes the read worse). Each swipe should take 1/2 to 1 second. Each time you want to swipe at a slightly different angle. Hopefully you'll get around 5 good swipes and it will learn all of them for that finger. If you did it right, it should consistently recognize your finger on the first try most times.I mainly use my thumb, which seems the most logical option for quickly unlocking and then handling the lock with one hand.There's no way to remove a single fingerprint, as far as I know. Be prepared to cry as you use the key fob and "learn" button to clear them all out and start over. I have added one other person to my padlock because we work out together. She was goofing off a bit when she first taught the lock and it had a hard time afterward recognizing her fingerprint, so I cleared it and we started over after a few weeks.One thing I like about this is that it is understated. It doesn't scream, "hey, kids! I'm a fun toy! Press my buttons over and over again to drain my batteries!" It looks boring and functional. I have yet to replace the two AAA batteries after months of very regular use.

I'm very happy with this lock. Great product.

It works with my print well however it has a hard time picking up my coworkers print.

Good idea but too big for the gym.

What a piece of junk. I bought two of these, one for me, one for a friend -- both broke almost immediately. $200+ down the drain.

Doesn't work very well, hard to program and takes several attempts to unlock - back to the drawing board - you have to drag your finger through it and that is a poor design -

GOOD AT ALL FATA FATI
