Negative Positive
Title: Stopped working after 20 minutes
Review: Worked great for 20 minutes and then no power. Nothing blocking it, just no power. Followed the recommendations and still no power. Also, you have to put these at least 2-3 feet in the air, on a level surface that is not wood, carpet or metallic - and lint free. What does that leave in most kids bedrooms? I used a rubbermaid tub that was as level as i could find. If it's not working b/c of that, I have no more ideas where to put this - well back to the store for sure. Don't know if I'll try again.
