I bought this in May 2011. I have had no problems with it. I bought it because it had the highest threshold of protection. So far, I have been luck and have not had any electrical surges that my computer equipment needed protection from. I especially like the orientation of the outlets and spacing so they can all be used.
We have had several power surges from lightning in the area and the Tripp Lite surge suppressor shielded my TV, receiver and Blu-Ray. The power surge did knock out our new washing machine, but it was not protected.
