Blanket arrived quicker than I expected. Thick heavy duty material. I had no doubts the blanket would perform as it should. The magnets used for securing the blanket are strong and secure firmly to back side of smoker. I have used the smoker 3-4 times before the blanket arrived and noticed temp flux around 10-12 degrees. Blanket has reduced flux to 3-5 degrees. I also feel the smoker gets to temp quicker. I didn't have to wait as long for the temp to settle down.
I have used blanket when outside temp was 38-50 with light winds.
