I've found it pretty awkward. The sweet spot for mine isn't where the coloured dots line up so there's some trial and error in getting them to change nicely and they seem to drift out every so often.
I probably had unrealistic expectations, was just expecting them to work with no adjustments required after initial installation.
It's possible but it came on a new bike so should have all been set up correctly. It's been good after a bike shop set it up but it does drift out of alignment after a while. I've never tried another though so don't know what it should be like.
