the second cylinder is much larger, it fits the whole unit inside of it, giggle stick and berries. It pulls the entire package and you can completely feel the ligs getting pulled. I assume it is working cause only a month ago this was very uncomfortable but now it is no problem, even with increased hg. I can also see that it pulls out much farther into the cylinder. This is what is claimed by the manufacturer to be where you will achieve the gains in length.
Ahhh - so we have another ball pumper amongst us! :becky:
Now you said you had the pressure in this cylinder up to 7 in.Hg? Whoa - you are gonna hurt something at that level. A good pressure for pumping 'berries' is no more than 4 to 5 in.Hg. They need to be pumped at very low pressure for a sustained period of time.
