This is a great toy for couples who want to step up their voyeur & exhibitionist game. At a firm 2" diameter, it is going to stretch the average vagina and anus a reasonable amount to accommodate its size. So that should be a sizing consideration. We both are experienced in the stretching department, and we found the size to be very comfortable. Because of this toy's girth, we both found it to be pleasurable on the g/p spots.

For us, we found this toy to be unique because it allows your partner to see inside of your body. Especially in a well-lit room. You can see things you've never seen before! As your partner is stretched around the 6" circumference of glass, you can peer in and check things out along the way.

When fully inserted, you can look through the flared base like a viewing window. There is some distortion through the glass, and the lack of light deep inside obscures your vision. We played around with shining flashlights through the base with mixed results. I think getting a body-safe insertable LED light that went into the body before this glass would be amazing. If I do this, I will give an update to this review.

The toy is a very smooth glass cylinder. There are very minor imperfections in the glass as far as symmetry is concerned. But it is super smooth with no sharp edges whatsoever. It is a heavy piece of glass, and dropping it could render it unusable. This is definitely a toy for the bed and not the shower. Because it is glass, it is easy to clean.

Overall this toy is a very interesting addition to the toy box. We have nothing else like it. Being such a large piece of glass, it holds temperatures for a good amount of time- soaking it in hot water- or putting it in the refrigerator. Its size/heft for the price makes it a very good value.
