Er32 collet holder
It looks good, but I have not checked it for concentricity yet.
P**E
mine has to much run out in it
The collect holder don't run true the shank will run true but no way can I get the taper to run true

Couldn’t clamp collets in place
I couldn’t make it work with the collets I have. The collets inserted into the extension okay but the tightening nut on the extension barely engaged the threads when attempting to clamp the collet in place.

0.005" runout
Was advertised as '0.0003" accuracy' ...whatever that is supposed to mean. I noticed visible runout, so I got the shaft running true within 0.0005" and measured 0.0050" of runout on the inside taper. I was pressed for time, so I reground it rather than return it. It appears that the part was both eccentric and egg-shaped.
