Before the Centering Rings Standoffs... even when i thought my Centering Rings were a straight... they were not!!! BUT NOW.. with the stand offs... they are straight as an arrow!!! Love them!!!
Using the “Tracker Case” makes for a safe way to hold the actual tracker BUT most importantly it is SO easy to move from one rocket to another!!!
I bought the medium size. Great product!! Easy to use and fins come out perfect every time! I wish I had bought this sooner!
