Ok - it's a good size for our needs.  I had a little trouble learning how to open it but after practice it has gotten easier.  I was somewhat surprised that I could not code my own combination. Also, I had asked Sentry Safe in an email if I could create my own combination and never head back.  I did not check my spam and will.  Over all it opens, it closes, it locks it unlocks.  It is sufficiently heavy enough that until I secure it to a concrete wall, it would be difficult for a bad guy to haul off.
