I found the mega pump to be very versatile. I not only use it for pumping my penis but I enjoy using it on my girl's nipples and clit. We used it with a 2 way buddy connector and the nipple cylinders for some serious nipple pumping. Then we added another 2 way buddy connector to have 2 tit cylinders and a clit cylinder going all at once. It has enough power for all 3 accessories and the pressure was even thanks to the buddy connectors. The pressure valve came in handy when she peaked out and begged me to stop. It comes with almost 20 feet of pump tubing so 2 or more people can comfortably use it together in a room. If you can fork out the extra cash this, it is a great product.
