The glass is solid and sturdy. I love the ridges on this dildo. I used this toy alone and started with the anal plug side paired with the Power Finger and wow! I had the best orgasm I have had in a while. I then used the other end and went slow. Sliding the shaft of the dildo against my clit as I inserted the dildo. When you go fast it gives the feel of a vibrator because of the ridges and I love that. I do have a VCH, so it does make a lovely crystal noise as it hits my piercing. I think it adds to the experience.
