We are having luck with the kdg-g3. I was locked on 10-12-09 and still locked on 10-17-09. We used a nail file a few times and so far no pain from beening cut into. Pull out is impossable. This cage is much easyer to wear than the cb-2k. I can cum with the Hitachi, but the wife has it. I could hump the bed and cum but with the short tube it feels more like a strong spray and not a very enjoyable orgam. Goddess asked me to take the cage off Monday 10-19-09 and we have not put it back on. My penis was red from rubbing of the kdg-g3 and the upper part was a dark color. Today 10-23-09 still little red but nothing like on Monday. The redness is understandable but the darker color on the upper shaft has me lost. Ask idea's ??
