Healthline does product reviews. This one, "Giddy Review: "Does the Giddy Device Work," written by Breanna Mona and medically reviewed by Matt Coward, MD, FACS, is about the new cock ring you may have heard about for treating Erectile Dysfunction (ED). To think I almost deleted the email....
Eddie by Giddy is a new-fangled cock ring, made from silicone.
The fact it comes in different girth sizes is a good thing, and the company promises to help any guy "resize" if the original purchase doesn't fit properly. (Though, the website does offer help in sizing.)
It's an FDA Class II Medical Device, which means it's been reviewed but not tested. You might be tempted to try it. But, at $238.00 for a 2-pack, the price alone may be enough to make you lose your boner.
Especially when you read down the article and find out it will need to be replaced every 2- 3 months. Whereas, a typical silicon or metal cock ring online, or at your neighborhood adult store, may run you $5 - $10 and pretty much last forever.
Additionally, it carries the same caution as any other cock ring which is used at only the base of the shaft.
You should only keep it on for 30 minutes, maximum. If you develop trouble, seek medical attention immediately to have it removed by a doctor.
Depending on the type of ED (yes, there are different types, read the linked article) you have, a cock ring may not even be the right solution for you.
