Solid fingerprint door lock
After locking myself out of my house, I decided it was time to change my locks to smart devices. I wanted a door lock that allowed for fingerprint and pin. The positive features of this lock are:*Fingerprint reader*Passcode PIN*Physical keys for backup*Backup power through USB ensures no lock-out even if batteries die (and it is the current usb-C, not micro jack)*Smartphone APP, which can greatly help in programming (registering multiple pins, fingerprints, temporary codes, auto-locking, other functions)The installation instructions were good. Lock and door handle seem solid, with no wiggle or loose play in movement as other handles have had. App works well as makes registering fingerprints and pins easier than programming with codes on the lock. Fingerprint reader works relatively well, but sometimes need to hold finger in position longer, or move and reset a few times to accept–do wish it was a bit better/more accurate, but its not bad. May try to re-register another print (same finger) which sometimes helps. It auto-locks within a few seconds, which is secure, but sometimes annoying (but you can change setting if desired).Seen a few reviews that state the lock is worthless and anyones fingerprint can unlock it, which was worrisome before purchase. But, this is a safety feature and clearly stated in the instructions: if pins and fingerprints are not correctly registered, it will allow any fingerprint to work to keep you from being locked out. You MUST register those pins/fingerprints correctly before the lock can function!Cannot determine how long the batteries will last at this time, and of course how often the lock is used, autolocking mode, ect. makes any claim meaningless. Mine has been going (with constant auto-lock) and a few unlocks a day, for 2 months with no issue so far.I like the door handle lock for its color choices, and fair price for the many features, which all work well.

Edited: Only put these on a door you know you can physically kick down. Print scanner is garbage.
Easy to install and the knob looks and feels great. However, the print reader is really picky about angle and print condition. It misreads more than it approves and so you end up scanning three or more times each time you want to enter.Edited down to one star after 2 1/2 months. The scanner on this handle is maddening. I have four prints registered in the software… both handles I purchased followed the same pattern: first day – opens fine with my primary print. Second day – gets really picky about the position of the print. Third day – stops working for primary at all but works SOMETIMES for secondary print. Fourth – stops working for secondary at all and doesn’t open with any print at all.Dry hands? Won’t open.Sweaty hands? Won’t open.Grimy hands? Won’t open.Just washed hands? Won’t open.I suppose this means it’s a really secure handle but if you put it on a door that you need to open with any regularity I guarantee you’ll find yourself contemplating just kicking the damn thing in at some point.Too late for me to send these back… I suggest you don’t waste your money.

Amazing Smart Lock
I’ve been using this fingerprint smart door lock for a few weeks now, and I’m seriously impressed. The installation was straightforward and took under 30 minutes. The fingerprint recognition is quick and accurate, and the option to unlock via app or keypad is super convenient—especially when guests come over.Build quality feels solid and premium, and I like the sleek, modern look it adds to the door. Battery life has been great so far, and I love that it alerts you when power is low.Great value for anyone wanting to upgrade their home security without breaking the bank. Highly recommend!
