Query: Great Smoker, Just Doesn't Hold Up

I have had 2 of these smokers within the past 2.5 years. On both units, the adjustable power source broke within 1.5 years of purchase. On the first unit, the heating element that attaches to the power source was also ruined.The warrantee was 12 months from the date of purchase, and no luck with the manufacturer after that period (I called). 50 dollars to replace the broken parts. I bought another unit instead, just 13 months after that, the adjustable power source has broken again. This unit was kept under a cover, indoors, when not in use.I love the ease of use of this smoker, and the final product it produces, it just doesn't hold up.
