So as I promised so many people in chat, this is going to be a personal review of the Progasm Jr. I say personal, as I understand that everyone is unique, and each person reacts to particular models differently. As such, I'm starting with the disclaimer that these experiences may or may not apply to anyone else. This was purely my impressions, my feelings, and my sensations from using this devices.
First, a material description of the Pro Jr. It is made of the same material as the Progasm Black Ice, so those familiar with the "soft" plastic should know it's a bit more comfortable than the classic plastic. The almost glass-like feel enhances the slickness when coated in lube, which promotes movement in the rectum. Overall, has a very polished look, while still being surprisingly soft.
Next will be a discussion on design. While many are wondering about the differences between the Pro Jr and the regular sized Progasm models, I don't feel I can give a fair or accurate comparison since I don't have any other Pro models. Instead, I will compare to features of the Helix and MGX, as those are the models I have and am most familiar with.
