Bests & Worsts Reviews from Amazon

This device is unreliable and dangerous to have. I installed in less than 24hours added brand new batteries and got locked out on 110 degrees heat. All happened because I took my dog out to pee. As we tried getting back in, it no longer worked. He was freaking out and we were both on dangerous heat exposure. I broke my window to get in. Please do not buy this product. It defeats the purpose to keep a key on you when you installed brand new batteries in less than 24h prior.
