Good vibes, soft texture, lighter than expected, inner sleeve is not solid silicone ... I would guess 1/8 thick sleeve and then the working parts behind the sleeve leaves a little air play. Warming feature= decent. Depth= 4 inches worth of penatration vibration. Vibration scale = I'd rate this at a medium vibe intensity. Sound= vibration sound low, but loud suction slurps if used as a stroker. Clean up=hard to get to bottom with just fingers, clean immediately. Jiggles/flicks or small twists seemed to get best results while inside over stroking, unless your into real loud slurping :) Good Purchase in the $70-$100 range.
