The problem with this 'Industrial Strength' velcro is that it doesn't stick to the surface if you use it with something heavy. Used this on an unfinished wood cabinet to hand a power bar from it, but it kept falling off where the second strip of velcro was stuck. It could be a problem with the type of surface (unvarnished wood), but I haven't tried anything heavy on other surfaces.
Works great for hanging lighter stuff, used it to hang a set of paper blinds and velcro my wii sensor to the top of my TV and never had problems with this. You do have to cut it into strips though, precut strips would be handier.
