You cannot perform most of the pictured activities because there is no flexibility (at least in the grey to black range). The flexibility does not match plastic bands, so there is very little range of motion to perform the exercises. Sure, they will be durable, but that is kind of like saying a block of steel is more durable than a rubber band; of course, but if you try to tie up your hair with a block of steel, you're going to have a serious headache.
