Query: Difficult to use properly....

This was very difficult to use. The channel for the cord was not really large enough (and I was using a Belkin Surge Protector bought at the same time). The strip was so curled that it took a long time to get it to lay flat enough to apply the double stick tape. You might consider laying it out flat for a couple of days before you try to use it!!!
