Review: A quality product. - This product performed as I wished. I was disappointed in a previous purchase, from a different provider, as it did not have sufficient tension. At 81 years old, with the age related fall in hormone levels and consequent decease in a once upon a time intense sense of erotic excitement, it is nice to be able to induce a good firm erection when we want it to happen, and have it last as long as my lady wishes to entertain my body in hers. The previous ring lasted about three years, as I lubricate the mounting cone and cylinder of the vacuum pump with water soluble KY jelly prior to slipping the ring over the cylinder.
Review: TINY - This thing is TINY. Non refundable, complete waste of money. Look elsewhere
