Old review:
This lock didn't make it through a single Ohio winter.
I needed to get into the shed in January and couldn't get the lock open. Eventually a lot of pushing and pulling worked. Then it wouldn't lock again, even after I brought it inside for a week to warm up.
Unreliable. Avoid.

Reviewed in Mexico on March 19, 2024
I have been using the Master Lock 178D for 3 days so far and I am very impressed with the quality of the lock. The material/durability is exception for the price you pay and programming the lock is a breeze - it took me 2 minutes. In addition, the shackle is thick enough to discourage a thief, as it would take a significant amount of effort to cut this lock. Overall, I am very satisfied with the security and experiencing using this lock and would highly recommend it.
