I have 2 standard ones which work the same as the one you have,they work better with the red razor rubber they kill soft rubbers especially on wooden frames. The best way to cut the rubber is just inside the clips no letting the rubber go over the edges,it'll make the rubber last longer.
When you cut the rubber correctly I've found they work well,at first I cut the rubbers over the ends and it was awful so went back to standard self dog eared squeegees. If you go on YouTube there's a guy on there Neil I think his name is he's done a few videos on them and explains what I mean.
