The singe biggest advantage: no more blowing past the pot hard stops. Their size is awesome too.

Paul -

Because they are magnetic, how much do you need to worry about proximity to motors with these? The datasheet talks about not mounting two of them closer than one inch without shielding in order to avoid crosstalk, but I was wondering if you had any experience with larger mag field issues?

The magnetics are certainly a bargain compared to the optical equivalent!

Thanks.
