Disappointing double oven

2/5
Thermostat in main oven faulty from start, had to be replaced. Red temp indicator light goes off way before desired temp reached, it goes on and off 2 or 3 times before temp achieved. Timer beeper sound very quiet, you can only hear when standing next to oven (my hearing is acute). Cakes do not rise properly. Not a patch on previous Bosch oven, we thought we were getting an oven of similar quality considering the price.
