Waste of time
My husband and I thought we would upgrade our gym locks. What a waste of time. They were unpredictable. Sometimes they would open and sometimes not. Sent them both back.

Good ( so far).
Easy setup. Clear instructions. Working well so far.I have tried a few options for similar locks and they haven't worked well. Hope these do.

Too big for backpack use
I ordered this to use for my backpack and it is too large to fit in the holes.

I charged it and went to the gym, went for a swim, and then it did not work! had to have it cut off
There should be a warranty for replacement!

Doesn’t work
Had it 6 months. Used twice. Had to cut it off the second time. Waste of time and money.
