Like other reviewers I found out the hard way that it does indeed partially block one of the outlets which then can only be used by the smallest plug-head like a lamp cord. I have an AC adapter and a fat TV power cord going into an outlet and I can't use this surge protector with them together. I would need to buy a short extension cord to accommodate the surge protector and even then it would be a tight squeeze into the outlet. The older design was square and fit perfectly. I have an older one on my other TV with the same set-up and it fits fine. Why they changed the design and made it taller is beyond me but they screwed up! Hey Tripp Lite! Ditch the tall design and go back to what works. If it ain't broke don't fix it!
