Pros... Great quality product, strong suction (excellent clit pump), easy to use, seems like it would last a long time, and each sucker has it's own on/off switch.
Cons...the vibration wasn't as strong as I would like - I would liken to medium strength of a regular bullet vibe. Also, the tubing isn't adjustable (the tube running from nipple to nipple doesn't adjust. So if your boobs are far apart - like mine- then the suckers shift and pop off frequently.)
Note: The pump isn't a gradual thing either, one good pump and it's at full sucking capacity. This might be too intense for some people but my partner and I have played with pumps before and I quite liked the intense feeling.
Overall it's a good product but doesn't work the best for me. We've only played with it a couple of times so maybe with some practice with placement it'll get better. I would recommend it for sure but just be mindful that it doesn't adjust.
