Ruby G was my first glass dildo, and what a joy it was. If you're worried about size, this is still stimulating without being overbearing. If you're looking for girth, this probably is not the toy for you.
It's a gorgeous color and is just shy of 7 inches in length; about 4 inches in circumference (the ball end).

For me, the only problem that I had was the tilted end intended for the G-spot stimulation. The tilted end was a bit painful after continuous use in a session, so I found that using the ball end against my G-spot was much more enjoyable. It also gives you a little more girth than the tilted end allows for.

Like all glass toys it's great for temperature play: Run it under hot or cold water to change things up. Another benefit of the glass was the ease of cleanup. I would just rinse it after use with warm water and soap, and store it in the convenient satin-lined pouch that came with it after drying it with a paper towel.

All in all, it's a simple yet satisfying toy that can be used with a partner or alone. It's great for oral sex instead of using fingers. It is also thin enough to be used anally on men or women. The best thing about it was its simplicity: it can be paired with other toys like clitoral vibrators or bullets. You can also use it in the shower!

The only other negative thing about this toy, and glass toys in general, is that there is a possibility of it shattering when dropped. I live on campus in a dorm and dropped it on my bathroom floor. Having to explain to my roommates they had to watch out for glass was a bit odd.
