Review on Enhanced Precision in Workholding - Techniks Super Precision Collet Accuracy for Industrial Power & Hand Tools by Lokesh Das

much higher quality and weight and better material than the cheap ones that came with my chinese 2.2kw spindle. thought it was ok to play with the chisel a bit before blocking. no - other "cheap" collets are more than half the price of this one, so getting a better one is no problem. It's an excellent product and without the game mentioned it's much less likely to break in my opinion.
