TL;DR: a brilliant cock ring for stimming
Solid cock rings need to be the right size, especially for estim - as they need to make good contact with the skin. ElectraStim make this product in a variety of sizes so most people should be able to find a ring sized correctly for them.
This ring is particularly good for two main reasons:
First is contact area. These rings are nice and wide which means you get a decent contact area the pleasant sensations that come with that. However, if you're looking for more painful stinging sensations this can still be achieved by using a powerful stimulator and turning up the power.
Second is electrogel or lube, which improves contact between the electrode and the skin. The problem is that with many rings this often dries out and you have to pause your stimming to re-apply. But the width of this product means that the electrogel dries out much slower. In addition it contains several small holes around it's circumference which act as small reservoirs for excess gel. So with this product you don't have to interrupt your fun as often, or even at all, to reapply conductive gel.
My only slight criticism is the connector. It's perfect for connecting leads, but it does protrude from the surface of the ring. That's a shame because without such a connector this first rate and very comfortable ring would be great to use even when you're not stimming. However I don't feel I can knock a star off for this as it's not marketed as a stand-alone cock ring and it's perfect at doing the job it's sold to accomplish.
Finally, the ring I bought was a discounted "factory imperfect" one. It took me ages to find the imperfection: a small scratch on the outside of the ring, where it does not come into contact with the skin and so does not affect safety or performance in any way. From other manufacturers I've received items damaged far more than this yet they were deemed good enough to sell at full price - so this speaks to the high bar that ElectraStim set for the quality of their products. Thank you ElectraStim!
