5 stars - NN Reversible Brass Detent Rings for NN3 MkII Panoramic Head - Great Customer Service By Mim VERIFIED BUYER. I haven't had a chance to actually use the rings. I'm sure they will do the trick. I just wanted to mention that I purchased the nodal ninja starter kit and it was missing the rings. (I'm not sure how many were supposed to be in the kit) Anyway, I contacted customer service of the issue and they promptly sent me a set of seven no charge. I was pleased.
ADMIN NOTE: We include 2 rings with each kit (15/0 + 45/60)
