Glass does cost less than the Njoy stainless . Glass can break. Njoy will survive drops , fire and earthquakes.

I don't have any glass and been leery of them. Njoys prob heavier also. Perhaps others can give you their opinion. I remember DancerKittyKat doing a review on one recently. Perhaps pm her. less

I am a guy but I have heard that they get a stronger climax/orgasm and increased pleasure. Also I have heard that it can push on their g-spot.
