Different Progasm Models = Different sensations?

The ICE and Ivory are probably the same but I visualize ICE's bubbles during a session and that makes it a much "hotter" partner. My response is a pair of very whorish nipples when I use the ICE.

The ICE and Ivory are a bit easier the forward quadrant of my outer sphincter than my old Red Classic (non-ICE) Progasm. Since the shape of these three tools appears to be the same, the difference is probably the result of how the ICE & Ivory slide in my canal.

I use Ice when I have alot of time. The Progasm Jr. is my go to device most of the time.

I think it's all mental. I've owned the ivory and had a great time with it. However, I like colors and variety-I have had the red, and I'm about to purchase a blue one. The colors go along with my mood, which causes my body to react in different ways. At some point, I too, will purchase the ICE. It looks like a lot of fun as well.
