The Space Finger
She chose this product, and can provide a more useful review of it as a whole. My involvement was in testing the cover as an enhancement to my digital manipulation skills.
I slipped it on my middle finger (for best fit and because that seems to be the closest I have to a clitoris radar, which means I can find the thing about .005% of the time) and applied a little lube. The result was akin to wearing a condom, if said condom were made of the same material as jelly bracelets. Due to the thickness of the material I pretty much lost all sensation of feel and had to make my best guess or have her guide me. In the end I felt like it was a bit redundant since using the actual toy would have been less work and probably would have achieved better results. I ended up taking the thing off, and the contrast of being au natural was striking.
The Space Finger is not out of this world.
