### ⭐⭐⭐⭐⭐ Very powerful and good quality
*by O***R on 18 February 2023*

Used it couple of days and it's very powerful I don't feel like I'm peddling upgraded from 5 magnet. I've 48v 14.5 amp battery and it does 50 KM. Can't reduce PAS sensitivity on this one

### ⭐ Didn't work
*by S***L on 12 January 2026*

Didn't work

### ⭐⭐⭐⭐ Worked after some tinkering
*by A***Y on 24 October 2025*

Didn't work for me, possible wires are in wrong orientation. Edit: Had to de-pin the connector and find the correct orientation for my controller which luckily only took 3 attempts. The teeth on the backside of the sensor meant to bite the inside shaft and hold outer ring in place were too short. I've had to improvise, ziptied the wire securely to the frame so that the tension holds the sensor in place. After all that headache it does now work well enough. Longevity is likely not good but time will tell.
