Was a bit "iff'y" about buying a glass one of these but took a chance and glad I did. Got rid of all my silicone ones as they can start to smell a bit after a while even with thorough cleaning.
The thing I like best is you can warm it up or cool it down and can comfortably wear it all day long no matter what you are doing !
Beautifully made, sleek and smooth and very easy to keep clean. Excellent product on all levels.
I really suggest being cautious with this product, especially if you are planning to use it without anyone else around - I discovered that base actually *doesnt* prevent it from slipping in too far, especially if lubed - in fact, its possible to lose the entire thing, and its not easy to extract once that happens. Its a pity, as it feels great and is lovely to use.
Hits the spot and doesnt get in the way while working on your partner. Highly recommend.
