I agree that the bun and roll mix leaves a lot to be desired - dry, flat and hard. Not like the pictures in their catalogue.
I, on the other hand, really liked the muffins and I was able to avoid higher carb foods because of them. The bread mix is also quite good once you get use to the sponginess. I made sandwiches with the bread mix instead of the bun mix.
I preferred the white bread over the sourdough and I think I ate the banana muffins?.
Good luck.
