Which stainless steel restraint should I purchase?

I’m just starting out in this. My wife and I have spent the last few months strengthening our bond, which included two sexless months (though I did masturbate a few times weekly). Now that we’re back to regular activity, I’ve slipped into old patterns that are straining things between us.

I plan to propose an FLR arrangement where I wear a chastity device around the clock, only released when she desires intercourse. Although I don’t do sports, I go to the gym and cycle regularly, plus there’s my job and social life to consider.

Which is the best starter device? I need a hinged base for quick locking and unlocking. It needs to be secure enough that I can’t escape it—I’m reliable 99% of the time but not perfect. I prefer the aesthetic of chrome bar models. The Stainless Steel Chastity Cock Cage, looks like a perfect match for my needs. The BON4 seems capable as well, but its appearance isn’t quite to my taste.

Do you have any thoughts on these two options? Or is there another device that might serve me better?
