Best answer yet to that old question.
I bought this zipper in June of 2012. Haven't stopped using it. I bought a bigger one instead. Who gets tired of easier ,better and faster. I still like a rotary for nasties.I give it a year maybe a bit more, folks will get just as tired pushing a zipper as they do a wand. Then we'll have another new/old renewal of rotary extractors.
