I've had my PM II for a few months now. It's a great pot. The mold guide is great for most boolit molds. Sucks for Do-It lure and sinker molds. The PID is nice and holds set temp very well, even with a big fan keeping my fat butt cool. The minimum flow rate is a bit higher than the minimum flow rate on my original PM. If I were to remove the lock nut I could get the flow rate down to the same as the PM.
My biggest gripe with it is there is no on/off switch. Also to keep the PID in good working condition you're supposed to set it to 0 when you're done and not unplug the pot till it's cooled. With a full pot this takes a couple hours at a minimum. There's some fan noise from the PID but for us old shooters it's not bad. Helps mask the tinnitus.
Overall I've very happy with the pot. I caught it on sale and would not hesitate to buy another if I ever have the need for three pots.
