How good?

I have a g-spot glass wand with bumps rather than ridges.

I got mine pretty early on in my sex toy exploration. I have been inlove with it forever. It milks my g-spot quite well and gets me squirting like crazy. It's so smooth when it glides in and out compared to silicone toys which have a bit more drag or friction.

If you would be intrested in a glass toy there are some really nice inexpensive options that can give you a taste of what these are like.

And a fun little aspect of glass is that you can play with its temperature (cool/warm) depending on what you like.

I guess if it doesn't work for you, it is still kind of nice to look at.

Wow, that's an expensive one to get if you're not sure you'll like it. I have the Pink Double G. I like that I can use either end. It's my first glass piece and very affordable.
