Query: Disappointing

After only using this grill a few times I have already thrown it out. Almost immediately the temperature selector knob came loose and ultimately failed to set the temperature at all rendering it useless. It was perpetually stuck on low. In addition it is extremely difficult to clean. I love the way it cooks so next up I am going to try another brand with removeable grill plates. Save your money on this one and go straight for one of those.
