CenryKay 2PCS 3590S-2-502L 5kohm 10-Turn Rotary Wire Wound Precision Potentiometer, Precision Multi Turn Wirewound Potentiometer,with Adjustable Resistor Counting Dial Rotary Knob

Like others say, the knob doesn't fit (regular knob, not 10-turn knob). Every knob in my parts bin fits fine so it is the supplied knob that is too small with an ID of 5.98 mm.. The shaft of the pot is 6.25 mm, a reasonable size. Otherwise the quality seems good so far.

These are quality. All around good product

This pot works but a couple of important issues. First, the dial mechanism uses extremely small lettering and hard to see unless you are 12. I am thinking that they didn't want the dial mechanism to be any larger than the pot which limited the size of the lettering. No reason that they had to be the same size. Second, the tiny set screw that holds the dial mechanism to the pot shaft is very easy to strip and will fall out if you missed the shaft and turned it too much. When you reinstall the set screw to try again, make sure it is gently inserted so as not to strip the threads. In any case, install the dial in some location which will allow you to find the very tiny set screw in case you turned it too much. Lastly, do not assume the three terminals are the same as the three terminals in single turn (other other ten turn) pots. The center is NOT the wiper. The wiper on these (and other similar units) is the terminal furthest out and a little taller. The first two terminals are each end of the fixed resistance. This setup is embossed on the body but you have to notice it and be able to read it. Aside from the above, good pot and good value.

Pots work good, but the knobs don't fit. I had to drill them out.

The knob does not fit the shaft on the potentiometer. It is approximately 0.016" too small.Difficult to grip the knob in a 3 jaw chuck to ream it to the correct size due to the plastic outside profile.Would be much easier had the size been correct.Clearly, I did not carefully read the product description as it says the knob is a smaller bore than is the shaft on the potentiometer.

Amazon wouldn't allow me to not enter a star! Many dead spots in resistance values throughout the travel of the potentiometers! The counters have areas in their rotation that have added resistance (drag) while turning them. The potentiometers never hit zero ohms (or even close to zero) at either end of travel. Usually 5Kohms or higher! I believe these are factory rejects!

PURE JUNK! DID NOT BUY THESE! One of them had an open winding inside and the knobs they come with don't even fit the shaft. Chinese junk.

Because it is an over priced piece of junk. Fell apart during installation. Should of went with Ebay.

Thank you
