Will never buy another Euro-Pro product again

The oven looks good, but it does not work. I tried to cook a number of dishes, but they were always undercooked. I checked the actual oven temperatures and found that the oven was consistently 140-150 low. In other words, when I set the oven to 300 degrees, the actual temperature is between 150 and 165 degrees. Additionally, it takes more than ten minutes to toast a slice of bread.
