BOJACK 12 Values 60 pcs Variable Resistor 100 to 500K ohm 3296W Multiturn Trimmer Potentiometer Assortment Kit

Not need to worry about the quality. They are good.

It's very handy to have a good assortment of trim pots at a relatively cheap price.

Good product. Arrived in good condition.

I'm using one of these to control a PWM motor controller's speed, and it works well. My set contained all of the specified trim pots (none missing). I have no trouble recommending this.

So first, the good: they seem to be a decent product and there's a good selection. What you need to know: the screw orientation is opposite of what you expect. Normally you turn the screw allthe way clockwise to start with the highest resistance. These are the opposite. All the way clockwise is highest and adjust down turning counter-clockwise. I don't even want to go into how long it took me to figure that one out.

Good selection and quality of components.

Genial no tengo que ir cada rato a la electrónica cuando cambio de diseño el circuito y lo reemplazo

They're within spec and work famously, I would definitely order again
