Genius idea, rock solid protection.
I purchased this safe for anytime I have to be without my 2A - hospital visits, airport trips, etc. I feel confident that it will keep my valuables safe from theft. In addition, the idea to make it look like a booster seat is brilliant, as it would not arise suspicion of potential thieves. After seeing their stress tests, I knew I could confidently leave anything in my vehicle and come back to it still intact.
My only suggestion is to include rubber lining on the top or base from the factory, as riding around causes a noticeable sound - like a metal can full of bolts jostling around. Once I added the rubber, it's silent!
