Rated 5 out of 5 by from Plug n play install means a lot to a tech handicapped senior I could not believe how easy it was to install; just plug n play basically! It certainly gives me peace of mind knowing that it is working. I'm very happy with it. I will definitely be back when I need to buy another.

Rated 4 out of 5 by from Pretty good for the most part. Besides the occasional trashed package, everything else is pretty good with them, from tracking to shipping.

Rated 5 out of 5 by from Never a problem! My unit has been in continuous use since it was received and I have had absolutely no problems with it. If we're going to be away for more than a day or two, I just turn the power off and back on upon returning. It's comforting to know that it provides a barrier between my equipment and the danger from mother nature.

Rated 5 out of 5 by from Full protection, best value The system does everything I want- protecting my computer from brown-outs and black-outs. It is money well spent. Spending less just doesn't protect the computer from power glitches as well.
