Iām using StealthForMen, a high quality vac attachment /hanger. It can take a while to learn to put it on and you need excellent suction to use it with high weight. The parts wear out over time. Well, just 2 parts wear out the most/ 1- glans cap, 2-vac chamber seal attachment/ the device the vac chamber plugs into. The next device that wears out (but not as often as the first 2) is the sabreskin. I have never had a vac chamber break but ive had to replace a clogged valve before.
They have medical grade tubing- something called sabreskin, itās incredibly comfortable. It only comes in 2 sizes, 30 and one other (maybe 28).It is sticky in a good way and great for preventing slippage.
They ship their main device quickly but I have had bad luck with refillsā from worn out parts. I just spent 3.5 months waiting for my last oart refill order (as an example).
Itās a good device and incredibly comfortable, but itās on the expensive side. I use it as an ADS and most of the 0.875ā BPEL length gains I made last year are from this device .
then: 6" BPEL, 4.88" MSEG, 4.88" BEG
now: 7.625" BPEL, 5.5" MSEG, 6.5" BEG
