Check this out! This is a pretty good item, except, the key and instructions are locked inside!!!!! I contacted Amazon.com about this and they said this is common practice for Solar Group. They've gotten many calls about this issue. We tried calling Solar Group directly but their offices are closed. All we could do was laugh at the sheer stupidity. A mulitmillion dollar company actually locks the keys and instructions as a normal practice.
