I was very excited to get this grill, as I was looking for something I could use both indoors and outdoors.  But I am rather disappointed. The griddle is aluminum and tends to warp. Enough so that the grease runs towards the front instead of in back to the catch. You can’t even use the silicone accessory for making egg muffins as it can’t lay flat on the grill so the eggs just run out underneath. I do like the dual zones and digital temperature settings as well as the cover. But can’t give it a good rating because of the warping.
