Seloky 20 PCS (Five Resistance Values) 5K-100K Ohm Knurled Shaft Linear Rotary Taper Potentiometer with Black Knob(WH148) Kit

You will have to measure and mark them yourself. I marked them with a Sharpie after I measured them so I only need to measure them once. Instead of getting 4 of each value I got more of one type and less of another. One would probably never know because they come all jumbled together. Even though the case has separate compartments, they just come filled with the one type of knobs that comes with the kit. So I just rearrange the values into separate sections for ease of identification going forward. See picture. They should come marked and already put in separate sections.

I installed this to regulate 21v output and several things are wrong.It’s not linear. After a little turn it dropped to 7v and fluctuated around on the voltmeter.

Bought these for a school project.Went to use them and 2/4 of the 10k didn’t work.Went to replace the non-working 10ks with a 20k and the first one we tried ALSO didn’t work.You had one job

Absolutely junk. I have already replaced 3 in circuits that I’m building/experimenting with. I would never dream of putting one of these in a customer’s repair. Just buy the real thing the first time. Digi/Mouser!

Good product for the price

Great value for a potentiometer and knob assortment. The assortment has the commonly used logarithmic values used for guitar effects pedal building. The knobs are great. The case is an added bonus.

I purchased this for my son (he’s 14) because he wants to learn how to circuit bend. He thinks it’s pretty cool for experimental things.

Product is as described and each one is labeled so you can tell them apart. I use these for DC motor speed control and other diy projects. But they have worked for me with no problems.

Well packed good price used for project from book.

If you're a builder like me, you can't go without this kit of variable resisters. You'll need then to achieve the right value resistance. It saved me a lot of time when designing an experimental circuit. Believe me you need this.I recommend this highly. Michael Rossetti.

No complaints. Needed a 20K pot for something so got this box of pots, it will come in handy with its sturdy box. The solder tabs actually can fit into PCB holes too, so either board mounting or panel mounting is possible.

I have had absolutely no issues using these with a microcontroller but if you try to use the normal wires that you plug into arduino pins, you'll find that the connection isnt very good. Once you actually solder a wire to the pins it works flawlessly but for temporary connections during testing it can be a little finicky.

Really good quality stuff, and case keeps everything together. Definitely worth iut
