I wasn't sure about the pressure-wave suction at first, but combined with the vibration it's honestly the best clitoral stimulation I've tried. The 7 modes give plenty of variety, though I usually just stay on one.
I wasn't sure about the sucking sensation at first, but the combination of pressure waves and tapping got me there faster than anything I've tried. Seven modes is more than I'll ever need, though switching between them mid-session is easy enough.
The tapping function caught me off guard at first, but after a couple of tries it became my favorite of the 7 modes. Only thing is the suction is quite strong even on the lowest setting, so I wish there was a gentler starting point.
