Limitless Potentiometers

[987HighRoller]

Hi,
I've been experimenting with limitless potentiometers....and have found them to be a little unreliable. Has anyone else used infinite rotation potentiometers?? If so, what kind and were they reliable? We are just trying to find another sensor other than a 10 rotation potentiometer for rotation measurement. This is because we had something like 8 potentiometers break on us last year, mainly because they get locked inside due to load on the shaft . We were also thinking of encoders but are afraid of using too many interrupts and messing with the interrupts already used by sensors like the camera and gyros. Any advise?
Thanks
