Query: Flaky piece of crap

This product started okay, but just got worse and worse over time.Turns out it's full of plastic gears rubbing against metal and the plastic wears down, and some actuators won't click and open the safe anymore. So after a year or two it barely ever opens.Search for "Sentry Safe won't open site:[...]" on Google. Read all the horror stories from people agreeing in the comments.Now I finally got mine open again, but it won't close.Worst safe ever.
