Had several of these ever since they came out. More useful than a conventional grill and MILES easier to clean (just wipe with kitchen roll) which is another key part to this.
Lots of comments about it 'drying the meat out' but I mainly use mine for bacon and sausages. Both types that are better without all the excess fat they have in them, and the perfect way to crisp up bacon! Also good for panini's / burritos and a healthier burger.
Obviously if you're using it for steak you're doing it wrong - get yourself a cast iron skillet for that (and never wash it with soap).
