My buddy has being using his for what seems like forever, he has never had any problems with them that I know of, I swear they are starting to fade a bit.

I like to use two large strips of velcro as long as the width or length depending on which way I run it. Always remove the rubber stubs. I also buy the stuff off ebay as you can get great prices for a whole wack of the stuff. If you don’t use enough velcro you will know as the pedals will move a bit, of course I get overly energetic sometimes and maybe a little rough :p
