This is a basic cock ring. It doesn't have any special bells or whistles; it is just a silicone ring. It's basically going to do nothing for using it on a dildo, but a man will find an increased size and sensation assuming he fits.

This is not adjustable, but it does stretch some. You will need to measure it before purchasing. No seriously, measure. It will save you a lot of pain and frustration.

Because this is just a black silicone ring, it is super easy and discreet to travel with.

I purchased this specifically because it is made of silicone. I love the safety rating of 10 that silicone has. This does have 2 seams that run along the inside and the outside of this ring, but they can't be felt at all when wearing.

It's totally smooth with a small amount of drag. It's very flexible, but has a small amount of stretch compared to other rings. It has no noticeable smell or taste.

My partner that doesn't shave found that this pulled his hair quite painfully when he was putting it on, taking it off, and even while wearing it.

I have two male partners who both tried this (we are poly and sanitized it!). The first is above averagely sized and found that this was actually painful when placed over both his shaft and testicles. After moving it to his shaft only, he found that he lost sensation due to it being too small.

The other partner who is of average size and girth couldn't comfortably wear this over his shaft and testicles either, but the ring was too large to do anything when worn only on his shaft.

This is a pretty discreet design. I purchased the black one, and it is just a flexible ring of silicone. It isn't intimidating, nor does it really scream "SEX TOY" either. This is a nice product in theory, but in the end is only work for a small portion of the population. This is not a one size fits all ring.

This has no vibrating attachments at all. It's just a basic ring. If it is a little large, you can use it to hold a bullet to your shaft which can work for some, but I don't like that sensation.

This is made of silicone. YAY! Silicone is a non-porous material that can be boiled, tossed in the dishwasher on the top shelf, cleaned with toy cleaner, mild soap, and warm water. Silicone is a great material for cleaning.

Silicone can not be used with silicone lube, nor can it be stored next to silicone toys. Doing so will cause your toys to melt, and no one likes that.

This came in a small circular plastic clam shell. It doesn't have any naked people on it, nor does it say cock ring on it. Instead it refers to it as a c-ring. The back explains how to care for silicone and use this product.

Over all, I like the packaging. I am storing the ring in it because it doesn't take up a ton of room.

This is a good product IF it fits. It didn't fit either partner, and they are dramatically differently sized. Overall, this could be awesome for beginners or more advanced users that are looking for something basic, but please make sure and measure before using.
