Didamx 280Pcs 100 ohm- 2M ohm Variable Resistor Potentiometer Assortment Kit

I'm very happy with these. There's a lot of them at a wide range of resistances, and they each sweep through nearly the whole range from 0 Ohms to the full resistance value. Just be aware that they are specified as having a +/- 20% tolerance, so if you need something on the very upper end of the range for a particular resistor, you may find that it doesn't reach it. For example, I tested a 1 Megaohm and found that it only reached to 940k. I'm not worried about this, since there's plenty of them available, and since they're all adjustable I doubt I'll run into a situation where I can't get to the value I need. They adjust fairly easily, just be careful to use a screwdriver that fits well so you don't strip out the plastic on accident.

Spot-checked several of these, and they tested within tolerance and varied properly from 0 to max resistance. Case is sturdy and secure enough to prevent contents shifting into incorrect compartments. Labeling on each unit is clear and legible.Good assortment, good value. Recommended.
