I recently installed this smart electronic mobile app controlled Bluetooth fingerprint door lock, and I'm impressed. The installation instructions were a bit unclear, and I encountered a missing part not mentioned in the booklet. Despite that, I managed to install it myself. I even ended up ruining a screwdriver while removing the old lock, but it was worth it. The fingerprint and number codes worked flawlessly on the first try. I found it easy to program, and the doorknob feels sturdy and not cheap. One thing I would suggest adding to the instructions is a reminder that the knob won't open the latch until it's plugged in and batteries are added. It took me a while to figure that out, but maybe it's just me. Overall, I'm extremely satisfied with this lock and will be purchasing more for my other doors.

The investment in this door lock was definitely worth it. The product is excellent, and the digital reading of fingerprints and passwords works flawlessly. I haven't tested the tag or app-based opening yet, but connecting the lock to the Tuya app was a breeze. The lock itself provides excellent security and eliminates the need for a key, which is fantastic. I loved this product so much that I bought another one.

I found this product to be good, and the installation process was easy as long as you have all the necessary tools. The lock looks great once installed and operates smoothly. However, the written instructions were poorly composed and confusing when it came to entering the personal code. Overall, a decent product with room for improvement in the instructions.
