Biometric scanner is very temperamental - GunVault SpeedVault Biometric Handgun Safe

I received this as a Christmas present last year and have used it all year. I should have returned it for something else but really fought hard to like it...to no avail... the safe works great to "keep little" hands away from my weapon, but I am concerned that in a time of crisis I would result to my back-up in another location. the Biometric scanner is just not dependable. I am retired military and so I understand the necessity of muscle memory. That's why I have attempted to practice opening this device at least 3 times a week. most times it takes me 3 swipes of my thumb for it to successfully read, sometimes it doesn't read it at all.
Bottom Line: Do NOT buy this safe until they have perfected the fingerprint scanner.
