I purchased one of Dennis's original textured units. After about a year, over a couple month period, I noticed that around the back of the cooker cracks were forming. These eventually deepened to form large cracks, and I couldn't get my cooker to seal any longer. I sent pictures to Dennis. His immediate response was "My bad, I'll take care of you". I made up the difference between what I had paid and a brand new latest gen cooker, and within two weeks, my brand new cooker was chugging along at 250F!
I hope this doesn't get my reply deleted, but the difference between Dennis's definition of "Lifetime Gaurantee" and "he whose name shall not be spoken" is immense! My mexi-K fell apart, and his response was "I'll send you some patching material". I won't even go into the wait time for a new cooker over there.
