Stay Hard Donut Rings do a simple thing and do it well. As long as you're not expecting any bells and whistles - and with a bargain price of less than $5, you probably aren't - these rings deliver just what they claim in a convenient, efficient package. They're perfectly designed to bolster stamina and staying power. The rings are quite stretchy - heck, you could probably wrap them around a Coke can if you wanted and they would stay in place without damaging the material. Though very durable, the feel of these rings is not as comfortably organic as some of the more high-end male playthings. You're certainly aware of the rubbery feel of the ring, which might impact your overall experience depending on individual tastes and preferences. Nevertheless, this is a minor complaint, particularly since you get three rings in the package (clear, black and blue) and can switch them around to increase the overall lifespan of the set. At such a reasonable price, this collection from Blush Novelties is another essential!
