LLtronation Handle-Style Fingerprint Cabinet Lock, Smart Biometric, Matte Black, Waterproof

This little handle is smaller than I expected. I like that it opens with a fingerprint. I can’t seem to figure out how to get it off of factory settings, where any fingerprint will open it, so the instructions could definitely be better. I’m sure I’ll be able to figure it out if I mess around that a little more. Seems like it will be easy to install, as well.

Of course, for the price, you're not going to get something that can keep the most determined of thieves out. But it's simple to operate and works every time I've tried it and it's strong enough to keep kids away. So, as long as that's your main concern, I'd say this thing is worth it.

Great product, works great on my top dresser drawer for controlled access. You really have to concentrate on the programming part, its open access until you get a fingerprint to register then open access ceases. The supplied usb simply bypasses the registered fingerprint and gives temporary open access again until unplugged, so keep it safe. Installation requires handyman level skills and tools; programming requires concentration and some basic tech skills.

I saw other reviews saying the fingerprint set up process was difficult. I've installed tons of stuff like this so I took a chance thinking it couldnt be THAT bad. I was wrong. I almost had to send it back after an hour of repeating the instructions, OVER AND OVER AGAIN. First off, the directions are in broken English, so it is a little confusing. No matter what I tried I could NOT get the device to go into the mode to record fingerprints. I was doing exactly what it instructed but it just would not work. The way I got it to work was to plug my own usb-c charger in at the step that said to use the little usb-c "key" that it comes with. By pure luck, I tried that and then it worked fine. The only tip I would give is to record the same finger MULTIPLE times from every possible angle. Before I did that it would take several attempts for the device to read my finger and open. Overall, I am happy with the product. But some better instructions would go a LONG way.

It took a little while to figure out how to measure the distance from the front of my cabinet to where the lock would engage the lock jam, but after installing another one on another cabinet, this one was pretty straight forward. You do have to put a hole in your cabinet for the wiring to fit through but that's understandable. We have IKEA cabinets and it works great on them. The fingerprint function works flawlessly. Once you figure out how to program your fingerprint in, it works awesome. I'm a dude, so I want everything to have pictures rather than reading all kind of instructions. The instructions were a little confusing but overall able to be figured out. A video would be even nicer to show how to program it in. However, once I got it programmed with my finger, I was able to program my wife's figure and it works great and accurate every time. It's nice that you input several fingerprint placements so that in case you don't get your finger exactly in the middle, it will still recognize your fingerprint. Over, I'm very satisfied with this product.
