I bought this for my husband to use for smoking meat and he has after a few uses gotten used to how to use it. We use it all year round and when you put hickory wood in the bottom it gives your meat a nice flavor. I will say that it wasn't the most expensive so I probably could have gotten one with a few more specials, but this one works fine for us. Performance It does what we want for our meat and gives us a nice result. As long as you take care of it like anything it will last a long time. Versatility Its rounded, so a little odd to move, but not really a problem. It takes up less space than a grill and smells quite nice when going. Ease of Use It has a little door on the side where you put the wood and you just need to make sure you have it closed. When cooking never open the top unless its done as all the heat goes out, instead when making sure its still has wood, use the little side door. Ease of Cleaning Again if taken care of not any worse to clean than a grill. Durability Its a solid piece and very durable. Design Only thing I find is its shape makes it a little harder to move. Otherwise saves space.
