Review: Works fine and if you follow the instructions - Works fine if you follow the instructions. If you set it up, how do you think it should work and it works for anyone and you think it’s just a pressure plate then you haven’t set it up correctly and you did not follow the instructions. I thought the same thing until I read the instructions. Make sure that you do it from a few different angles like it says in the directions and that the beeps and flashes happen like it says in the directions and you’ll see that your other hand does not work unless you set your other hand up as an additional user.

### ⭐⭐⭐⭐⭐ Works fine and if you follow the instructions
*by D***D on August 4, 2026*

Works fine if you follow the instructions. If you set it up, how do you think it should work and it works for anyone and you think it’s just a pressure plate then you haven’t set it up correctly and you did not follow the instructions. I thought the same thing until I read the instructions. Make sure that you do it from a few different angles like it says in the directions and that the beeps and flashes happen like it says in the directions and you’ll see that your other hand does not work unless you set your other hand up as an additional user.

### ⭐⭐⭐⭐⭐ It’s very good
*by Y***A on August 5, 2026*

It’s easy to install and set up

### ⭐ No Fingerprint? No Problem! It'll Open Anyways.
*by A***E on August 15, 2025*

If I could leave zero stars, I would. The only positive thing I have to say is that the installation process was quite simple, but everything else? Terrible. The "fingerprint scanner" is actually just a hypersensitive pressure plate, so anyone can use it to open the door. I realized this when I accidentally went to open the door with my other hand that I hadn't "registered" any fingerprints on & it unlocked. I gave it the benefit of the doubt & thought maybe I did & just forgot? So I had my roommate, who hadn't touched the doorknob at all yet, try it & once again ... DING! It unlocks. We did at least get to make a fun little game out of it & tried coming up with the weirdest way to open it. The ones that got the most laughs were a vase, journal, remote, her thigh, my foot, a laptop, another doorknob & my dog's paw. Since I discovered how useless the knob's "fingerprint scan" was, I decided to just take the batteries out & use the keys it comes with instead so I could actually, y'know, lock it? NOPE! Turns out that without the batteries it's even more useless & doesn't lock AT ALL. Basically, unless you're looking for black metal door knob with a fun gimmick but is utterly ineffective at keeping people out, it's just a complete waste of time & money.
