Delivery a little more than a month to ulyanovsk. Resistance 10 kohm. I bought it for altering the charger for a laboratory power supply. Everything works fine, the adjustment is very smooth, you get tired of twisting the handle. Using the lever from the side, you can fix the adjustment to a more rigid or lock in one position, the handle stops spinning. In general, the goods pleased, fully suitable for my purposes. Waiting for the board from china, to reduce the voltage, later add feedback about the work as a whole.
