Hi can I ask how you are finding the BON4M cages? I’ve ordered all three and looking forward to playing around with the different rings and spacers. I’ve got a good idea of size through the CB6000 and CB6000s kits but read a few reports of rust and rough edges. Enough really positive reviews to decide on ordering though!
I also have all three, I like them quite a lot. Sometimes the ring pinches, but generally feels really good. Metal is the way to go.
Thanks for getting back, I can’t wait to get the small on and try the micro also. The longer version should be fun for tease and denial I hope! My CB6000s is almost at the point of splitting above the opening if I get a little over excited so worried about overnight wear now as you can imagine!
