Having just received and tried out this delightfully frustrating toy, I would thoroughly recommend it. I lasted seven hours before allowing myself merciful ejaculation. I'm now locked back in and trying for 24-hour abstinence, despite the stimulation of crossdressing
I got this as a replacement for the cb600s after u had some serious comfort issues with it.
This one is much more comfortable thanks to the design of the ring and how it connects to the tube. However when I put it on first I didn't notice some sharp edges left over from the manufacture. These cause a couple of very painful areas.
These edges were easily removed by a bit of sand paper and a sharp knife and now I have no issues with it what so ever.
Cleaning could be easier but realease once a week is good enough for me to stay hygienic.
Overall a very good device that is comfortable for long periods. Would definitely recommend this one.
