I just recently purchased and used them,they do work,I think I wrote," They cast like a rocket,and land like one ".I caught several fish using the smallest rocket bobber,and will keep them in my arsenal,I do like the slip to non slip adjustment.That said,I fished the rocket bobber,vs a generic thill mini bite recently to see any subtle or glaring differences.
The rocket bobber can cast a mile,allowing me to keep a distance from nesting gills,but it's rather noisy entrance caused the bite to be slower ( imho ).the generic mini bite,won't cast as far,exspecialy in wind,but the near noiseless entry seemed to not disturb the fish,thus I seemed to get quicker takes on the mini bite.
I'm not saying one caught more than the other,I will use both depending on conditions,calm conditions,the mini bite or similar style float will be my go to.Less than calm conditions,the rocket would be better.As far as the rocket out catching a round bobber,that I can believe
