WayinTop 5 Set 360 Degree Rotary Encoder Code Switch Push Button EC11 Digital Potentiometer with Switch 5 Pin Handle Length 20mm and Knob Cap for Arduino Electronics Projects

I tested all five of the encoders and all were working fine. Not very high resolution, with only 20 pulses per revolution, but perfect for simple OLED menu control. I've successfully used them in multiple such projects.I prefer this style (threaded shaft with nut) as they're easy to mount in a box compared to the ones on a PC mount module.Great value at two bucks each, with knobs included.

TYhey work just fine.

Used these for an Arduino project. They are very smooth with noticeable detents and the button has a nice click. 1 star removed because one encoder sometimes would register rotations in the opposite direction when spinning fast.

Aren't working as they should, they register the wrong direction at least half of the time. exemple as i turn left it goes left-right-right-left-right. tested 2 of the five, canno't return them cause i needed to solder wires to it, stay away!

This rotary encoder works reliably and has a strong click feel as it moves through each position. The legs are quite malleable though and I was not able to pin them into a breadboard without them popping right out at the lightest touch. Once actually in a soldered circuit though they have worked very reliably for me
