"This was my first cock ring over 5 years ago and it is still running strong. The vibes are not super "throbbing," and they lack some of the variations that others have. I’m giving it 4 stars because it continues to work after 5 years and it does offer good pleasure.
I believe this cock ring is more for the woman than the man, but I have to admit I use this primarily for self pleasure. My wife enjoyed the novel thrill of it, but found it a little irritating over time. I think that is personal to her and not for everyone. She does enjoy using the magic wand, but that is a deep throb and she only needs to use it for 30 seconds or so before she is done. This won’t provide that sort of instant reaction, but it will enhance a prolonged experience.
The quality is very high. The silicone of the 1.25” ring easily stretches around either just my balls or my cock and balls together. I am told I am a little thicker than average, but I’m definitely not huge. It is usually comfortable, but it can get uncomfortable over time. I think the recommended time is 15 minutes or less, but I’ve definitely gone for 30-45 minutes. After that long it can hurt. It is relatively quiet compared to the other toys I’ve purchased.
One big challenge I have with this, and most cock rings, is that it is hard to change the pattern. I like to change the pattern multiple times so a lack of remote is a big bummer. If I have it on one pattern for more than a couple minutes I get numb to the effect.

For comparison the Adorime Vibrating Penis Ring with Adjustable Buckle has 10 good and strong vibration modes that were a true game changer. Unfortunately the Adorime lasted for about 3 months and then the buckle broke. A month later and the Adorime’s vibration was gone.

I have purchased two other cock rings: the DAYTHI with the little rabbit ears and the Cafatop. The DAYTHI had a similarly weak vibration and lack of variety to this IMO unit, but lasted maybe 2 months. I was very excited for the Cafatop since it has a remote and is supposed to have a stronger vibe. The remote and the vibration worked great (not as good as the Adorime), but the Cafatop lasted maybe 30 days at most.

I used the IMO all through the time I experimented with the others and continue to this day. I can’t say it is my favorite, but it was probably the best for me to start with."

"Tried this since it was recommended by a husband and wife author team,super easy to use and light. The vibrations were not very strong but that heightened the feeling and prolonged the experience. Well worth it."

"Just received it and decided to have a quickie sex session and um, can you say holy cats?
Both of us are EXTREMELY pleased for the first trial. Will update as time goes on, but so far so good."
