I ve used pumps in the past. Electric ones. They were AWFUL and stopped working way too fast!! I absolutely LOVE THIS product though!!! It works really well, the suction is fantastic, works for nipples and clit. The suction can be super strong at first but the release button is there so you can instantly release a little air and set it perfectly. It holds well and stays until you decide to release it. I m incredibly impressed because my experience with these haven t been so great, in the past they were always way overpriced, broke quickly, didn t work properly and then just stopped working after a short period of time. This product doesn t have those issues. Super easy to pump, super easy to release, holds perfectly. Absolutely 5 stars. I can rarely say that.
