I was having a very hard time making ribs in cold weather. Used lots of pellets and had to use 40 degree increase in temperature to maintain 230 degrees. Received the blanket,installed it in 2 minutes. The outside temperature was -2 degrees only took 15 minutes to preheat the grill to 300 degrees,put on 2 racks of ribs and set the temperature to 240. Grill maintained 230-235 on half of the amount of pellets as before. Expensive initial cost but very,very worth the price.
