The Barska did work fine for me. I am Male in my mid forties and the unit installed and worked for me just fine. I was able to set the unit up and installed it without problems. The problem came when it came to set up my wife's finger prints and we were not able to get her finger prints to recognize. Called the Barska Rep and I was told that those with fine finger prints will not be able to have their finger prints read by the optical recognition. A safe that my wife can't access is useless to me. Especially if we are ever in a situation where she needs to access to the safe when I am unable to do so. Opticsplanet had me ship the unit directly back to Barska at their expense and the UPS driver even came to my house to pick up, happy about that. Still waiting on my refund at this point but it has only been ten days. Just make sure that you test the unit thoroughly with the thirty day time frame for returns.
Pros: Good in theory but technology not there yet
Cons: Barska Rep stated finger prints were to fine for the optical recongition to read
