my experience:

​

Do not get this style

​

but get this one

​

or this

​

Both handbrake had issues with sensor / magnet. had to move them on both handbrake because even calibration didn't help. 1st one was also binding but 2nd one has larger footprint. 1st one had worse placing / positioning of the arduino bord and eventually the usb plug broke off :(

2nd one is made better.
