It is a nice smoker , very easy to use but unfortunately  not working as described. Soon as you fill 2 out of the 3 racks with meat, you won't be able to achieve a more than 100F for a very long period of time . I waited for more than 4 hours to get at about 180F. As a suggestion to Cuisinart, I think that you should use a more powerful heating element or insulate the box better. The outside temperature was around 0C.
