I got mine Wednesday. Unfortunately I scraped some skin off the edges of my glands on Monday and it’s not healing very quickly, so it made testing the new pump a bit of a pain—literally :D
I tested out the pump Wednesday afternoon despite my sore glands. When I first turned on the pump it just about ripped my cock and balls off, because the release value wasn’t releasing at all! I adjusted the release screw every which way, and still, no release. I finally determined that in order for the valve to function properly, you need to have the thumbscrew almost all the way unscrewed.
Oddly, most of the range that you can turn the screw = release valve 100% blocked. Then, when you finally get to the mostly unscrewed position, it suddenly becomes VERY sensitive. Just a tiny fraction of a turn makes a huge difference in pressure. This makes it rather difficult to adjust, because just a little bump to the thumbscrew will swing the pressure enormously. It would be much easier to precisely control the pressure if the full range of the screw was used for adjustment rather than only about 5% of it.
After finally getting the pressure set to between 5 (release) and 10 (top of stroke), I did a 30 minute session without getting any donut effect. Someone else posted here that they did an entire hour at 8 (not sure if that was 8 average, or 8 Max at top of stroke) without getting any donut, so I tried a full hour session 10 hours later. I guess I pushed my luck that time because I ended up with a huge donut that took 36 hours to subside.
Yesterday I did two 20 minute sessions at the same pressure with a bit of jelqing in between and got no donut at all, BUT I also wore least constricting cock cushion (E) just below my glands as a donut prevention alternative to wrapping the circumcision scar.
I initially tried to use a strip of that self-adhering Ace-style bandage to wrap the head as someone in another thread recently suggested, but it wouldn’t stick to itself after I got lube on it. That was a big problem because you need to lube your cock up well in order to prevent friction burns on the glands from the pulsing motion. In any case, the cock cushion worked great as really quick and convent circumcision scar/donut prevention wrap.
It would be great if they’d make a wider, even less constrictive, cushion especially for wearing below the glands. My circumcision scar is 1.25”, so the cock cushion didn’t over the entire area. I suppose I could try using two cushion (D+E) if I ever have a problem with the lower portion of the scar bloating, but so far so good. I think the part directly below the gland is the most bloat prone anyway.
The pump itself worked great, but I have a couple questions for the rest of you guys with XL=3000’s.
1) I knew that these pumps leak a bit of oil, but mine is leaking more than I expected. I can’t really use the extra storage space inside the case to store any other PE supplies unless I didn’t mind getting motor oil on them. How much oil do your pumps leak?
2) If I keep the lid closed, the pump arm bumps the top of the lid a bit at the end of each stroke—enough to raise the lid a ¼” or so if it’s unlatched. The lid is flexible plastic, so the pump still functions properly if I clamp the box shut. I just wonder if it will shorten the life of the pump running it this way. The pump is much louder than I expected, after reading so many comments about it being quieter than other pumps. They must sound like rockets launching or something! Anyway, it’s somewhat quieter running with the lid closed, except for the little thud sound every time the arm bumps the lid at the end of each stroke. Does this happen with all XL-3000’s, or just mine?
3) Does your valve function similar to the way I described? Because the pump is so loud, I’d like to put it in a closet or another room and lay down a really long stretch of tubing. I’m afraid to do this, however, because then I’d be unable to monitor the pressure. I can’t really “set and forget” it, because the thumbscrew on the pressure release valve is so damn sensitive that any little tap will throw the pressure range off a LOT, and I wouldn’t be able to readjust it with easily because the gauge is built into the case which would be in another room. I’m thinking of adding an additional gauge on the line right off of the pump. Anyone know where you can get just a plain gauge not attached to a pump or anything else?
P.S. The cock cushions are fabulous; much better than anything I’ve tried for keeping a pump after a PE workout. They are exactly what I’ve been searching for. They clamp the base firmly enough to really hold the post-PE pump for hours, yet are still amazingly comfortable.
