Since I think that Masterbuilt makes the best entry level electric smokers I chose to buy one fully aware of their short warranty period. I can't afford the more expensive, better-made smokers with the longer warranties anyway. .
But the skimpy warranty just goes to show that Masterbuilt is fully aware of all the problems that can arise with their smokers, they acknowledge that their some of their smokers are unreliable pieces of crap (mine is fine, though) so they've decided to keep their losses to a bare minimum. I'm sure they've got reports which show major problems will start to occur after 90 days either due to manufacturing defects or some of the yahoos who buy smokers and either never bother to learn what they're doing or start modifying the crap out of it. So, you're out of luck if you buy a Masterbuilt and because of various reasons in that first 90 days the farthest you get is taking it out of the box.
So, I malign Masterbuilt for having such low confidence in the quality of their smokers but I praise the company for marketing a very good and inexpensive entry level smoker, the MES 30 Gen 1.
