Bests & Worsts Reviews from Amazon

I loved this oven! Until it stopped working (no heat) after 3 months! I have been trying to get it fixed under warranty for 2 weeks now, without success. Is this always a difficulty when you buy things through Amazon? I will post an update, if and when I have any luck finding someone who will respond to me. If not, I guess this product is just a dud. *2 weeks later - still no luck getting any response to my problem!
