I’d tried a firmer ring before and it always felt pinchy. This one has enough give to stay comfortable but still snug, and the seamless edges don’t dig in. Honestly, we noticed the difference the first weekend.

Bought this for my husband and me after seeing it recommended. The silicone is very soft and doesn’t irritate my skin, which is usually sensitive, and the weightless feel is real. But after a few weeks, the adjustable slider loosens a little mid-use, so we have to pause and readjust more than I’d like. It also picks up lint if you don’t rinse it right after. It’s not a total miss, but for $56 I expected it to stay put better.

Came in a plain brown box two days early, and the silicone is smoother than I’d expect for $56.

The ring itself is well made, but the blue is a little more slate than the photo. It took us a couple tries to find the right adjustment so it didn’t slide during use. Once it’s set, it’s comfortable and does what it’s supposed to.
