Input:
I thought this was the machine I wanted, because it had a die-cast pan like the beloved Oster machine it was replacing. (Oster, unfortunately, has abandoned quality in the interest of cutting prices and satisfying the irrational consumer notion that a loaf of bread must be rectangular, not square.)
I was wrong. The heavy die-cast pan does make a better crust than conventional stamped pans, but this machine over-kneaded the dough (40 minutes altogether), resulting in a dense texture inside.
But the worst thing about this machine was the noise. The machine was driven by a toothed belt with matching slotted pulleys. Nothing wrong with that, except that Breadman engineers apparently thought this design eliminated the need for belt tension. The belt was loose, and it often slipped out of the notches during the kneading cycle. The result was a loud banging noise that resounded throughout the house. I could never use this machine on the delay setting, because the banging would wake me up during the night.
Customer Service just told me the noise was normal, wouldn't damage the machine, and I could try adding more water to the dough.
After trying 3 loaves of bread, I exchanged the machine for the Breadman TR2200C Ultimate, which is far superior and well worth the extra 30 bucks. I will miss the crisp crust of the die-cast pan, but otherwise the Ultimate is a better machine.
