Wasn't expecting much when I ordered because I'm a firm believer in you get what you pay for, boy was I shocked. The attachment was everything as advertised and made very good. I was expecting at least two scenarios after I purchased. 1. Shaft would have alot of vibration durring use and wouldn't be useful durring long carving sessions,......2. Shaft would have excess heat buildup during said long sessions. This shaft......hehe ok don't start.......exceed both my expectations on quality and durability. Made with quality materials and works like a charm. The only thing I guess I would love to see is an attachment to accept router bit shafts. Definitely worth a shot if your looking for a low cost carving attachment, suited my needs perfectly.*6 month update*After using this attachment for a little over 6 months now I have to say I'm pleasantly surprised. Initially after I bought it I figured it would last a couple weeks but its still working great minus one slight flaw. The output shaft has become slightly loose at the tip but it would be attributed to normal wear and tear. Also the quick change head has lost some of its knurling making it slightly difficult to grip. I would highly recommend getting a foot speed control for your high speed rotary tool with this. Makes projects a breeze.
