All-Star "bow Maker" Worth Purchasing?

[PeaceLoveCali]

I stumbled upon this website and I've had trouble perfecting my bows. Do any of you bow pros know if this would be a product worth purchasing? Thanks!

Honestly I think cutting a template out of cardboard is just as Effective (and wayyyyy cheaper) but I suppose it would depend on which part of the bow your struggling to perfect.... But I know of some people who tried the bowdabra and thought it was a waste of $$!
