If i was starting out i would most likely buy this but wrapping coils is absolute cake after you do it a few times and you can use a million things to wrap them on.

This is just another UNNECESSARY gadget to get three bucks out of you , but people like gadgets so it will sell well .

If your still wrapping Pro Tank heads, slipping a 1/16th drill bit in the slots is the easiest way , not sure if this one is as easy as doing that with it's much shorter length and heavier end piece.
