I was given a Gen6 and I didn't want it, nor any dang electronic measure. Now that I've been using it for 4 or 5 years I've changed my mind. The 505 and the M5 both get neglected most of the time. I use it mostly as a scale because I love my mechanical measures. However when single stage loading it dumps out +/-.01 of the set weights as fast as I can seat the bullets for my rifle loads. 99% of the time it drops -.01 grains of the set which is easily corrected by setting it .01 higher.
