Perfect fit, not so much for the first timer....
To put the size of this in perspective think of a small chicken egg. The gem is a very pleasant green and the materials are a very nice quality.
Personally, I find it slightly less satisfying walking around every day with it in, the base edges dig in a small amount as the thighs brush against it. Exceptionally comfortable as an insert and forget while lying back and pulling my muscles around it.
Cleanup is super fast and knowing it's S/S means I don't have to worry about confusing cleaning regimes.
This was a great little purchase. Well weighted so you really know it's there but low profile so you can wear it out and about if you're that way inclined. An excellent addition to stimulate.
