It does the job required replacement for the old perished rubber.
As a girthier individual it’s quite tight, but after breaking it in it fits well. Just wish the material around entry was a little more cushioned as it can be a bit painful when using the pump on maximum suction.
Provides a more air tight fit.
Initially a challenge to fit onto the pump cylinder so needs a little lubricant
Is quite tight, but with a bit of trimming works well.
Excellent addition to my pump. Far better than the thin latex the pump came with provides excellent seal
This coulda killed or unmanned me !.
Firstly, it's slightly too small for the pump i had, so required a hard stretch to get it on, then found the hole was very small. So I thought I'd pump my balls, like you do. Each teste slipped thru the hole with a blast of quickly fading agony like they'd been slammed in a large book (you know what i mean aye guys?) and it was then I realized I'd made a dangerous mistake. It felt like I'd been lassoed around my scrotum, and the cowboy was riding away at high speed. I couldn't for the life of me get this evil device off, my balls were turning interesting shades of lavender and the neighbours were becoming concerned by my falsetto screams. I eventually had to cut it off with the electric carving knife. I'm off machines and devices now, my hand is good enough for me, and way less likely to cause me permanent damage
