One event filmed in 3 hours. I had a firm grip on the gimbal but kept slipping, causing the gimbal axis to get stuck. I had to loosen and tighten every 20-30 minutes. Not to mention the shots went poorly but after this shooting I had no confidence in this grip. If I install it properly, I expect it to stay there. Good aesthetic design but terrible functional design. The little rubber pad you put inside doesn't work. He slips. waste of money
