Query: Worth it.

They work great. Nice and portable. However, I wish the cable were just a little longer, as some wall ports at hotels are higher up the wall. This strip just hangs instead of resting securely on the floor. Also, the plug glows bright blue when it's plugged in, which I really don't like. I think they tout that as a positive feature but I like total darkness when I'm trying to sleep.I got two, and I leave one in two different pieces of luggage so I don't forget to pack them.
