Well Lyn I have been so impressed with my "Slug" I ordered the "Max PR" version that they recommend for prostate survivors.
After a long delay (customs) and it arriving with the requisite customs description for the postman I can confirm the Max PR version is worth the delivery cost.
It really is way better than the old faithful durex ring, it is easy on, easy off, and doesn't "interfere" with the action.
One other major benefit, it isn't made of latex so my missus doesn't get an itchy fanny, that results in even more opportunities to make the most of our life together!
Firm Tech Max PR highly recommended!
