They work great with my 7-sp system even though they're designed for 9 or 10 speeds. I also like being able to just feel with my hand and know which gear I'm in by the lever angle. My hands are small so when I'm in the middle of the cassette and the shifter is sort of parallel to the brake lever it can feel weird to have your hand in that gap, though there's definitely room. Just something to get used to. Not that I throw the chain all over the cluster very frequently, but it's nice knowing I can shift as many gears as I want in one smooth motion, and I know exactly where to stop because of the visual feedback from the lever.
