Summary: The Isobar Ultra saved my system. Metal rules! Was running it ahead of a UPS with voltage regulation protecting a Dell System. Must have been a really bad transient The $50 Isobar sacrificed itself for a brand new $4,000 Dell System.
Summary: This is a good product suited for computers and printers or HDTVs with home Theatre sound. It is sturdy and made of metal. I did not use it for HD TV and Home Theatre. ( perhaps I may later). I used it for a high end tube amplifier and high end CD.
