I wasn't sure the double vagina would actually feel different from one side to the other, but it genuinely does. The material warms up fast and cleanup takes two minutes, which matters more to me than anything else.

The double opening actually makes a difference — switching between the two sides gives completely different sensations instead of the same thing every time. Cleaning takes a bit longer because of it, but that's a fair trade for the variety.

The double opening really does give two different sensations, which is more fun than I expected. Cleaning takes a bit longer because of the two chambers, but that's my only gripe.
