The added girth of about 35% is what surprised me most, and the soft elastic fit didn't slip or pinch once. Took a minute to roll on properly but after that it felt secure the whole time.

The extra 5 cm actually made a difference, and the soft stretchy fit stayed comfortable the whole time instead of pinching. The vibrating part was a nice bonus I didn't expect to use as much as I do.

I was worried it would feel too tight, but the material stretches enough to stay comfortable. The added girth is the part that surprised me most, my partner noticed right away.
