Bad product
Ordered 3 for use on telescoping arms, didn't expect to unpack a 3d printed product. Not only was the quality of build poor, the string winding portion would break after one or two pulls and required me to pull apart the assembly and manually wind the potentiometer. Not worth the purchase, if you or your team are looking to buy a string pot spend the extra on a better quality one.

Assembled String Potentiometer
Performed as advertised. Was easy to set up (creating a 3-wire Analog wire for Roborio and do a little programming).

Broken out of the package
Bought 2. Didn’t realize it would be 3D printed part. First one pulled string one time and it stayed out. Second one wasn’t giving reliable readings. Went with another type of sensor.

Review
Quality OK. I would have designed mounting base much larger to incorporate 4 screws and made housing thicker for unanticipated abuse.

String pot
Got two, installed as steeringangle sensors, they work great and you can't beat the price
