I have a Contender and I love it. However I'm also finding that the chastity lifestyle is working even better for my wife and me than I expected. If at 60 days we're both all in, then I want to get a second cage. First to have a backup in case something breaks on the Contender (unlikely I know). And second to see if there's something even better.
My priorities are:
As comfortable (or damn close) as the Contender. Which most of the time I can't tell it's there.
Definitely steel and I can wear 24/7/30 cleaning it in the shower without taking it off.
I have a JB and a WM. The JB is much easier to clean in the shower.
Past Devices: Curve & CB 6000s. Both broke, were repaired; then broke beyond repair. I threw the dreaded Spiked Chamber away.
Current Devices: MM Jail Bird, Cobra, MM Watchful Mistress, Holy Trainer v3, and a new Curve.
