The A-MAZE-N Expanding Tube Pellet Smoker isn't on the website yet, but I was lucky enough to catch Rhonda in a weak moment and was able pre-purchase one to try out. The tube came in the mail today and I got busy checking it out. 2 things immediately caught my eye; first is the tube is now an oval shape and the perforations on the tube are slotted and not holes. These are 2 excellent improvements in my opinion. With the oval shape, 2 issues I've had in the past are no longer going to be a problem. The tube now will not roll around. At times when I've taken the torch to the round tube, it would roll a bit, and I also had a couple of issues with rolling when I would bump the smoker. When the rolls happened, I would sometimes lose the cherry that was feeding the pellets. It's also MUCH easier to fill with the oval opening! I have carpel tunnel syndrome in both hands, and holding the tube and filling was tough sometimes with the round tube. Trust me on the easier filling, I filled and emptied this new one 4 times during this review. The slots on the sides of the tube will allow for much more air to hit the pellets during the burn process and they will also not clog as easily with soot, ash, and creosote. It also seemed to light and start the smoking process faster. The above listed "improvements" are on the expanding tube that I received today, I have no clue if these will be seen on any other tube types in the future. The tube's overall length, when collapsed is just a hair over 11", and when open, right at 18". Since I prefer to use my tubes more than my trays, this will give me some better options than I've had before. At times, the 6" was too small for the smoke I wanted to do, and the 18" was too long. It's hard to light 12" of pellets in an 18" tube, with the expandable version, this will no longer be a problem. When collapsed to 11", the tube held 11 ounces of Pit Master's Choice pellets. When fully extended to 18", the tube held 19 ounces of the same pellets. I didn't try other flavors or brands for the fill amount testing. I filled the tube, collapsed to 11", with pellets at 2:10 PM central and lit it off. I'll see how long it runs and provide a burn time update later. Over all, I think Todd has hit this one out of the park. It's basically several sized tubes in one, you can use it anywhere between 11 and 18" . Watch the website, the expanding tube will be added soon I've been told! https://www.amazenproducts.com I'll be smoking 2 chickens with this tube tomorrow, and will post the final results in another thread.
