It was one of the first things I bought when I got my Dutch Star. It has saved me several times from 'bad' power pedestals. I bought the portable, as I didn't have a lot of room in the power bay. Plus if it were to ever go bad it would be simple to send back. I've had it for 7 years and never had to return it yet. I do like their lifetime warranty.
You'll be glad you decided on this unit. ( I hate to sound like a commercial).
