The price. Easy to assemble for 2 person. The top metal  cover and the square body is already assemble, I would do 100% nicer then that, it was 3/4 inch out of square. It is cooking excellent, try to bourn the Charcoal well before put the meat on it and keep the heat at 400 to 500 degrees for 8 minutes (4 each side) for a medium 1" steak.
