I've had one of these for nearly a decade now, and I love it. I even use it in place of the regular oven when I've got something that needs baking that's small enough to fit, just because it takes about 1/4 the time to come up to temperature.

Since the bread is flat in there, it also makes it much easier to melt cheese on top of it without either getting the bread hot enough to melt it all by itself (which would surely leave it much browner than I like), or microwaving, which makes the bread soft and moist.
