Thanks for all the feedback. Well I have decide to use better an ADS Made by myself because it was impossible to find the sluice. I had purchased the incorrect one and thank God that there were no shipping to here so they refund me the money. And to be honest for me is really tortuous to use the vacuum chamber, I mean, I feel the gland really sensitive and is painful to use even the jeans. With this ADS connected to the extender is better. It allows me to be aware of my gland. I love this page to be honest.
