So far I am really liking the tower design of this surge protector/power "strip". Being able to select only top or only bottom or both is a bonus, no need in powering the whole unit if all sections aren't being used. Being able to charge/power multiple devices via prong, USB and/or via wireless connection gives a get deal of versatility in both the number and types of devices that can be supported. I don't think the size is conducive to travel, but I didn't purchase it for that anyway.
