I've owned my grill for about a year and have found it to be the best I've ever used. The infrared side burner is a great tool for hamburgers (don't have to light the main grill), browning hamburger buns and searing steaks. The four burners provide a large surface for multiple burgers, steaks, hot dogs, whatever. I've recently gotten the wood ship accessory for smoking and am looking forward to trying my hand at smoking a brisket. Having 4 individually controlled burners makes it easy to use indirect heat for slow cooking. I've found the temperature gauge to be a pleasant surprise. It doesn't give the internal temp for what's cooking, but is more accurate than those on other grills I've had in the past.
The grill is more expensive than a lot of the others that are available, but this is a case of 'you get what you pay for'. I'd definitely recommend buying it.
