My husband bought me this grill for Christmas two years ago. I use it all the time. The two features I use most often are the grill plates and the waffle iron.
The grill function browns beautifully. I have issues at times with items sticking though. When I open the grill to check on food, I open it very slowly and peer in underneath to see if my food is stuck to the top. I just reach in with a fork, or similar utensil, and break the food loose. You might be able to avoid this by spraying it with non stick spray.
The waffle iron portion is nice, but I haven't worked out the correct temperature just yet. My waffles have been coming out fairly dry and tough. They are cooked, but not quite the right consistency.
Honestly, I would probably have been better off keeping my original George Foreman Grill and just getting a nice waffle iron separately. I wouldn't say that this appliance is worth the price that was paid.
