I like the GunVaults, but I have had the boards on 3 electric GunVaults fail over the last 5yrs (they are just too much $$$ to keep having to replace every 1-2yrs, IMO) so I am sticking ones with a mechanical fallback.
I was using one of the MiniVaults with the backup key inserted at night (which made for a quick and noisy opening.) I liked the noise when the kids where younger because it was loud enough that it would wake my wife up when I put my EDC in it if I did not take care to hold the lid and open slowly -- and I felt certain my kids would make at least that much noise.
Now that my kids are slightly older, I have switched to matched NanoVaults so I can use the same key in my cars and in both bedside safes. It still makes a decent amount of noise when opened, though.
