The suction is way stronger than I expected and the transparent cylinder with the metric markings makes it easy to see exactly how far you're getting. Took me a couple of tries to find the right seal, but once I did it was worth it.

The sleeve inside feels surprisingly realistic, and the suction builds smoothly instead of jumping straight to max. I like that the transparent cylinder lets me watch everything and check the metric markings as I go.

The clear cylinder with the metric markings is honestly my favorite part, I can actually track the progress instead of guessing. The sleeve inside feels surprisingly realistic too.
