Query: excellent for business travel

This is a great little accessory for travelers. There is great space between the outlets so I can use them all at once with multiple differnt types of AC plugs. The only downside is the blue LED light on the wall plug where it says "Monster Power". If you put it in the right location, it would be a useful night light. However, it is a glaring light and very disruptive to sleep if you put it within eyesight such as plugged into the lampstand common in many hotel rooms. I find myself propping some type of notepad or other opaque material in front of the plug to block the light.
