First off, I really wanted to like the product but find it very difficult. Long story short I was send multiple replacement parts to resolve heat issues and improper meat probe readings. In all I was sent 2 meat probes (separate occasions), controller, heat pot, fan and yet again another controller. Finally the grill does work properly but this was over a 6 month span of headaches. 
Overall I do like how it cooks now that it is working but the constant cleaning and overall maintenance is a pain. This was by far the worst purchase I have ever made. I wish I would have just bought myself a nice propane BBQ.... this is just my opinion.
