Mmmm, I love my glass toy. It's my favorite!! I've named it Ira. :-D
It's easy to clean, it's versatile, it's cool when you put it in at first but it warms up nicely, and it's purty. I've never really cared much for vibrators, so I'm maybe not the most representative sample, but this beats vibes hands down IMHO.

I have the "Pure Pleasure" bloopy glass one about halfway down the page. Acrylic is also nice:

My friend D has the "Bloop Wand" one at the top of the page - she loves hers, too - calls it Pink Friend.
