Bests & Worsts Reviews from Amazon

Says weatherproof. Case says indoor or outdoor use. Had it outside running Christmas lights for a week and it filled with water after a rain and stopped working. I popped it open to see what was wrong and there isn't even a sealed surface in the part. How do they expect to keep water out!?!?? Luckily Amazon is awesome and gave me a refund. That's why I use Amazon right there.
