Experiences with precision collets?

Can anyone share any first-hand experiences with improved collets for Dewalt 611 routers?

I’m curious if anyone has upgraded to something other than a stock collet and been able to observe improvements in accuracy or finish quality or anything else?


I upgraded to Precise bits and purchased the kit with 1/4 and 1/8". I especially like their collet care cleaner/lube. I haven’t run any scientific tests, but they do seem better than the stock collet.

Doubt that I will go back to the DeWalt collet, the Precise Bits collet is much better. We use our SO3 in light production environment, so it gets frequent steady use.
