Hello, This is a very clean portable smoker without a scratch. Always traved and stored in the original box. It is the 1st generation and a link below is the second generation but I cannot find any differences in design or size. Used it around 10 times on camping trip but no longer needed. The plastic container was for wood chip to soak them in water. A great deal those that love the slow cook in the outdoors or smaller families without a place for a full sized smoker. Masterbuilt is a great brand, I even have the fullsized Masterbuilt in my backyard. P.S. Box is included. :)
