Check out Costco before you buy this. Masterbuilt Electric Smoker or MES for short are great, or at least the new one I bought is and from what I read everyone else here seems to like them too! But, I bought a MES 40 at Costco for $320 and a few days later saw this MES 30 at Homedepot for 300. For an extra 20 dollars I got a ton of extra cooking space. Also I did the boil test and the factory temp probes were only a few degrees off of my maverick, all my ITs have been perfect. I recommend doing a price check and going with the bigger one! Good luck!
