biometric has some issues, mostly they are a swipe motion so your finger print will not be left behind, however, they can fail if your fingers are wet or dirty (or covered with blood heaven forbid) I have a standard gun vault GV2000STD, because my work gun and off duty are different I can keep both in the same box and my 2 yr old is unable to access but my wife can. I screwed it into my night stand.
