I don’t know if it is better. People here have used it and gained, and not gained. Look at the auto extender site.
It’s just a different way to attach your penis to the extender, for some, myself included, it’s the only comfortable way I’ve found to do so. This allows me to wear the extender for hours without discomfort which I am hoping will lead to better gains. I’m going on the theory that the longer I can wear my extender the better the results will be. The noose and velcro mods never let me wear the extender long enough to get any gains.
Check it out here: http://autoextender.com/usorder.html look for Modified VacExtender 4, that’s the one I”m using and it’s awesome. You can also use the stealth cap found here: http://autoextender.com/upgradecenter.html , you will need VacExtender sleeve to go over it and hold it in place and you need the VacExtender Head to attach to the end of your extender. I use this setup when I’m going out in public as it’s much smaller.
There is a contact link in the upper right corner of each webpage on the site if you have more questions about the products. And no I don’t work for them I’m just a satisfied customer.
