Wasn't sure about the internal part at first, but the curve hits the right spot without any fiddling. The ring itself stays snug through the whole session, and the vibration carries through both pieces nicely.
The prostate massager curves exactly where it needs to be, and the vibrating ring stays put even when things get intense. Took me a couple tries to get the angle right, but once I did, the buildup was incredible.
The internal stimulator hits just the right spot, and the vibration adds an extra layer that’s hard to describe. My partner and I both noticed the ring kept things firmer than usual, which made the whole session last longer. Definitely earned its spot in the drawer.
