The low-speed stroking mode is surprisingly gentle for a warm-up, but cranking it up to the high frequencies really delivers—the rotation adds a whole extra layer that I didn’t expect. Works exactly as described, and the cycle through all ten modes keeps things interesting every single time.

The rotating modes add a nice layer of sensation, though I wish the speeds were more clearly labeled—took a few tries to find my sweet spot. Overall, it's a solid upgrade from my last toy.
