Occasionally but not often. In this case I can visually see the weight moving after every swing and the ground was nowhere to be found. On the sliding track you can even see where it is a bit discolored from the weight moving on it while being torqued in place.
I got nothing then. That's weird, but I'm glad Callaway is addressing it. I've messed with mine a little and adjusted a couple times for the 3-4 rounds I've used it and no issues so far.
