Used this on a two month shoot last year in Alaska and it worked great, but haven't been using it for a while so wanted to sell it to get cash for a new lens!  Unfortunately, when I shipped it back home there was some damage to the vertical axis joint.  Because it was still under the warranty period DJI assessed the whole thing and replaced all of the bad parts.  Works like brand new now.  Offering it at a low price because I made back the full amount renting it to the show I was doing.  It's really a great rig and far better than the previous model, which I still have!
