Query: Toaster Has Uneven Performance

I bought the new version of this toaster about six months ago and I have been disappointed in its performance. The toaster gives very uneven results, often almost burning one side of a slice of bread while leaving the other side barely toasted. The adjustments to allow different settings do not seem to correspond to the results -- the toaster continues to almost burn one side of the bread even at lower settings. One advantage of this toaster is that there is enough space for larger items such as bagels.
