Putting that devise in there, threading it through,then moving it out of the way to tension, then repositioning it for the next cross,you should be able to weave it by hand much more faster, and efficient.
Plus some racquets have 16 mains, others 18 mains to weave, along with the top and bottom crosses being shorter,(notice the demo did not even start the crosses on the 1st cross, and I'msure there is a reason),and using and fitting this tool in place,it seems to me that this is one big gimmick as far as I am concerned. Any respectable stringer could do much better than this gimmick, and use the money for something else like a cold beer after the job!
If you learn to string properly there is no worry about friction burn anyways, after all who even uses wax anyways.Fanning your crosses prevents any friction burns even with thin delicate multis. or nat.gut strings.This item is a joke!
The ads tool is about as great as the models fashion choice!!It certainly does not look like a professional stringer is using it, and not even installing the crosses in proper order.Their marketing is as much a joke as the product!It seems if they want to market a piece of junk, then they should have at least had a professional Voluptuous model dressed a little more revealing to do the stringing if they are not going to use a professional stringer.That way it would have looked a little more interesting.Bottom line I would not waist your money on this junk.
