Gun Safety For Homes With Children
I have always stored our gun in a safe since we have small children and this product has completely alleviated my stress about the gun getting in the wrong hands. Now I can leave it out and know myself and my husband are the only two people who can access it. We ordered during pre order and it took almost a month before we got it but it was worth the wait. Going to get my sister one for Christmas.

solid buy
Bought one and love it, still only 1 week in but it delivers exactly what it says. I'll do a full review after 90 days.

It changed my mind
Was a skeptic but thought the concept was cool so figured I'd give it a try. The material quality, products execution, and the biometric reads through lotions. How this is only $250 is a mystery.
