Oven not strong enough!

First oven arrived and was not working.
Amazon.com was very helpful to help with English. Thank you!
Second oven Seems to be working. Seems I say, Because the oven is not very capable with baking.

The space is very good at least for at oven of this type.
But WT 200 degrees food takes almost twice the time to prepare Compared with other ovens. Either there is a problem again or the oven is not meant for serious baking.
So lower resistance Seems to become half red.

In general by experience with this product is not the best. I only bought Because a friend has it and They are satisfied.
