Taiss 3590S-2-104L 100K Potentiometer 10-Turn Multi Turn Rotary Wire Wound Precision Potentiometer, 10 Ring Adjustable Resistor Counting Dial Rotary Knob

These are awesome for testing a pot connection just to see how much flexibility you could add to a 100kOhm connection, even if you decide to put a standard 100kOhm pot in the final design of a project. I built a guitar delay pedal using one of these, and the level of control I have over the time of the delay is phenomenal.The added knob helps with figuring out just how many turns into the thing you are. The pot itself gives you about 10-13 turns, and the knob basically goes from 1-100. Some other folks have complained about a lack of precision in the pot itself, but I haven't found that to be a problem with my projects.My only complaint is that they don't seem to offer larger ones—say, 1mOhm. With something like 1mOhm, you could use one of these to decipher just how much variable resistance a project would be most useful; once again, even if you don't use this type of pot in your final product. It also beats using a trim pot, although it does take up quite a bit of space.

The ten turn dial set screw does not engage the too short shaft even with just the nut and washers on it, let alone through any panel. The pot also gave strange ohm readings at one end of travel, (went to zero ohms and back up during last few degrees of rotation).

Pot and knob seem ok but the included hardware is wrong. the threads on the nut don't engage at all it just splits over the top.
