Can take a picture of your version of blower? :bsmilie:
please see link.
anyways.. seriously though, does any blower differ? it's just a rubber ball around a small thin thing that emits air. of course i can push the small thin thing into my rubber ball (and this sounds really weird now that i reread it).. but i think it's pretty hard to spoil any of these, and you shouldn't need too strong a strength of blowing!
