I have the same one Mike, and I find it serves all my jewellery making needs, the only thing I found with the quick release handpiece was that if the drill was trying to go through something a bit thicker and got stuck it would spin in the chuck. You can alter it a bit but it wasnt enough to make a difference. I wrote to Foredom in the USA and they send me a handpiece with an openable chuck, like a drill chuck, which solved the problem, and they didnt charge me for it which was a bonus.
