So, you actually modified it, didn't use it alone as a table hatcher. If it needs to be in its own box with insulation, then they might start making them that way. You had success because you tinkered and found what worked. Most people just put it on a table & let it go...I understand your irritation about brand bashing, but honestly, they do have a bad reputation, and its because people have difficult times using them "as is". I use my Genesis "as is" and it works without me doing anything else.
I really think that people buy the LG because its cheap, then they don't have much of a repeat business due to the difficulties they have with it.
Again, tell 20 people positive things, and 2 of them will repeat it, tell 20 people something negative, and they all will repeat it....human nature....
