Ok, I think I am confuses. Do the wall outlets have 3 prongs or two? I could have sworn the strip I took last year had a 3 prong cord on it that I plugged into the wall outlet. Maybe I just don't remember what I took. I never used it though. Never needed anything but the wall outlet and it was very easy to get too, no hiding behind the bed. I thought all power strips were three pronged.
