The Cobra II is a great system!I used it only 2 days after receiving it the first week of September 21 and was able to successfully complete a dynamic balance in one shot. Needing just the initial reading run and the adjustment run. Fantastic, smart system. Ive used two times since with superb results. And ability to make the reports and put them on the usb flash for easy printing or distribution, excellent. Now I just need some extra time to read and figure out the rest of the bells and whistles a little more. Thanks to all @ ACES for the great system and as always awesome support.
