First time hearing about that, that would be awesome!!! Any info what he has in mind??
If you worry about money and want to be sure I´d recommend the ab silicone since you can buy only the sleeve for around 20 bugs (if it´s between that and xleeve). It is a little sturdier than xleeve medium (which is quite durable), soft and soft-thick xleeves break easily if you are not careful. As I already said I had problems putting the Absilicone anti turtle thing on altough I´m pretty average. In the meantime I read a post from MOSman or something I believe which stated that he uses vaseline... I´m sure that´s a good solution but haven´t tried it yet since I don´t want to constrict my fast girth gains right now.
Also the Absilicone is a little shorter in lengh since it seems not to be made to cover the glans contrary to the xleeve. I just found another product of absilicone which only covers the glans
http://www.absilicone.com/index.php?route=product/product&product_id=54... so this is the same philosophy as xleeve in terms of
ADS only that it doesn´t cover your whole unit. I guess that brings it´s own advantages and disatvantages. But considering that you have the option to buy specific parts WITHOUT being a previous customer is a big + for Absilicone in my eyes.
