So we use what you see above on the left, the CB6000s. The small is quite important as all the advice is to go for the smallest you can cope with.
However we didn’t buy the actual original device, which is something stupidly like £100. Instead we found a nice copy on ebay for about £15. Seems good to me! I can’t tell the difference and hubby seems pleased it works well.
I don’t think it’s totally secure, he can probably pull his cock out if he REALLY tries, but for us it’s more about the psychological aspect, not about true imprisonment. And for just £15 it’s been quite revolutionary to our sex life!
The metal ones look fun but I can’t think they are really any more secure.
What do you use, any recommendations?
