Vampire drain was a concept which mattered a lot last decade, but by this decade no longer is a relevant factor.)

I think the concept is great for most items (lamps, printers, chargers, other computer peripherals); however, I really haven't figured out a way to use it with energy hogs like plasma TV's and DVD players.

I really love the concept of these surge protectors, and this has exceeded my expectations

The concept is great and when used on standard electronics, it seems to work well.

Very good concept and could save me a lot of money

Brilliant concept!

Didn't end up using the power saver as much as I thought, but the concept is great.

Overall, this device represents an excellent concept but with a very poor implementation.

Great concept.

Great concept, but usefulness is extremely limited.

great concept but be carefull the PLUGS DONT
