If you look at all the comments most people with bad reviews think it doesn't work.

To turn on you must remove plastic cover and press buttonThis would stop a lot of bad reviews as well as returns!

I do have to laugh at the idiots who wrote negative reviews, particularly the ones who claimed the surge protector never worked

While getting ready to leave a bad review I spotted one that said before you return it as broken, "pry off the clear plastic dome" and amazing, it works fine and it's now been several months of steady use

they work great - i like the round design
