### ⭐⭐⭐⭐⭐ Lock Isn't Waterproof.
*by M***D on May 16, 2020*

The lock works excellent until water enters the compartment it damages the lock, I purchased two locks, and the first lock worked over a year without needing the batteries changed out, once the batteries died, I opened the lock to change them out and it was damaged all inside from rain, now the lock no longer works, I contacted the company requesting a replacement, and I was told I couldn't get a replacement, and that would happen being in the rain a long period of time, to add candle wax?! Well maybe, I would consider that on a replacement lock, but they refuse. I just opened the 2nd lock two days ago, not knowing what the first one looked like insude, so Now I'm going to have the same issue with the second one. Bottom line, the lock was advertised as water resistant. I was offered a coupon...I'm not happy with that, I would like a replacement identical alarm lock, what I spent my money for. I would recommend for locking capabilities, but not an ongoing working alarm if it gets wet. Unsatisfied Customer
