Initially had problems with the controller but Z grill sent me a new one. By Oct 2019, I purchased it in March 2019, the cover was ripped because of the sharp edges on the hopper. I taped on side and so far this year, 2020, I have had to tape the other side. The cover shrinks and when it’s put on and unless it is there are two people, you will tear it. The company sells no replacement covers so everyone is out of luck.
