This is awesome

From Darren

It's the best experience I've ever had while pumping, and ive bee though a few different types/styles of pumps. Who would have thought a sleeve insert could make suchba huge difference. The textured sleeve feels incredible, while still retaining the full effectiveness of pumping.. Could literally have gone for hours on the first session. Cant wait for my next. Highly recommend if you're either new to pumping or experienced. It's soft slick texture brings an intense new sensation while pumping which i havent experienced before, and does not have any harsh stretching feelings. The cushioned entry prevents the feeling of the solid chamber crushing against you (and your balls stay safely outside) Definitely a solid and highly pleasurable investment. Twist or rotate the pump while in use for even more delightful sensations...
