I've been using mine for over 3 years now and have had them on 3 different bikes during that time. Loved it on all of them and will continue to ride these bars for at least another few seasons.
The sweep and rise aren't anything unique but fit me super well and have left me with no complaints on my set up. Only thing I might add is a request for a 50mm rise bar, like the M9, but with a 35mm size option.
