Very cool toy. This was my first experience with pumps. Using it as a solo on-the-go situation is doable but not ideal, just a bit awkward. so I found it more fun to make it more of a procedural thing with a partner (which I find hot). I used it with the 3 inch clit cylinder and the vulva cylinder which are both fun. The pump itself is really sturdy, well-made, easy to figure out and clean. Definitely made my parts swell up in an exciting way, but would recommend keeping an eye on the time just so it doesn't get too raw on the bits ;) . Definitely a great addition to the collection.
