MYPIN Bluetooth Fingerprint Cabinet Lock, Smart Biometric Cabinet Lock, Keyless Hidden File Drawer Wardrobe Lock, Child Safety Electric Fingerprint Lock, DIY Wooden Furniture Privacy Lock (Plastic)

Physical installation is simple. However, learning to program in fingerprints and set up the Tuya Smart app isn't so simple. Instructions are crappy. However...once you figure it out, it all works as advertised. 1. When you're starting, any fingerprint will unlock it because none is saved. Press and hold the fingerprint you want to become master. Hold the finger there for a several seconds until the green light is solid. Then once you get the full green, lift the fingerprint off the scanner. Note: if you keep holding your finger there for longer than this (with a 'master' fingerprint), you'll reset all saved fingerprints. 2. When you lift fingerprint from the reader, the light will turn to blue. You then touch the reader with your finger for half second and then lift the finger. A green light will flash once quickly to indicate a successful read. Tap a few more times just like this until a solid green comes on. Your print is now saved. This process is similar to setting up fingerprint unlocking for a smartphone. 3. The first fingerprint is now your master. If you've followed the steps correctly, ONLY the saved fingerprint should open the lock. Check using other fingers that weren't saved to be sure. You should get red light. If not, start over until you figure it all out. 4. If only the saved/master fingerprints work, then you're successful. Repeat this process using the master fingerprint to get the solid green, then entering additional fingerprints (on blue light) following the same steps. Save one fingerprint at a time. Note: only the first three prints are master prints that can authorize adding new users. Others are only regular users who can unlock only.

Used it for wardrobe. Works well. Easy finger print setup. Could set up on app with some help from the manufacturer. Straight forward installation (done by a carpenter). We are planning to order more.

Great lock, works perfectly after more then a year of every day multiple use, batteries lasts in forever - I didn't have to change them yet. Only downside is if I have dirty, damaged, wet fingers, it will not open on 1st try or at all, but that's normal, not a defect. There is emergency usb stick included with it, to open it in this cases (or mobile app, which i don't use)

Pretty easy to set up but I needed something more sturdy for a door and something with wireless capability worked for my situation.

Instructions aren’t great but once installed this little thing is great. Easy to manage thumb prints and users form the Tuya app. I installed this on a snacks cabinet to keep little fingers out at night.
