Actis Band

Save your money. Go to the sex shop and get the adjustable constriction ring. They look like a lassoo made of surgical rubber tubing and have a bead that the loop goes through. It costs less than $10 and does EXACTLY what the actis band does. It seems hysterical that a "medical" company makes the same thing that sex shops have been selling for years and can charge a lot more!

Adjustable constriction rings are the best friend of every PCa guy battling ED. It turns the "almost there" into fully usable. Be sure to trim/shave pubic hair. All rings can rip hair out and ruin an otherwise great time.

I have never tried the Actis band, but have tried the adjustable constriction ring as Paul described. I have never found it to be very satisfactory. Even without hair getting in the way, skin still gets in the way, and I find it difficult to adjust without pinching -- ouch

I have found ordinary office rubber bands to be highly effective. Mine are around 2" diameter and doubled over, they give a snug fit -- I normally use four. They work with a cheap VED (pump) too, and are much superior to the horrible sleeves that came with mine.

You can apply at least some constriction before inducing the erection. Arteries (inflow) run up the center while veins (outflow) run on the outside, so constriction operates on the veins much more than arteries. For me, blood still gets in, but finds it harder to escape.
