Query: dissapointing product

I chose this oven because it seemed to have the large capacity that I was looking for. It has good looks, but each time I recieved a "brand new" oven, immediately had a problem. The first time, one of the heating coils failed to light, I was sent a new one but decided to use the "old" one, since it did heat up. After it finally died, I brought out the new replacement, It heated properly, but the door hinge broke & the door dangled. I decided to order another one, again for it's large size, & this one too showed defaults, none of the coils lit to indicate it was getting hot, plus I never heard the fan, (it was a convection oven) I am back to square one, looking for another convection oven, it won't be a Euro Pro.
