Query: Poor design

The dial for the timer on our first unit broke within 1 day, so we had to take it back. About 3 months later, the timer on the second unit broke for good, so that the unit never turns off and runs continuously - dangerous, in my opinion. Also, it does not toast evenly (the bottom is toasted darker than the top), and the temperature setting is not accurate - we routinely set it 25-50 degrees below normal to keep from overcooking food. Overall, cheaper units perform much better. On the upside, it has a larger capacity than most others.
