Query: Underpowered

I've used Braun shavers since the 1960s. The 1775 is the only model that is unusable. The problem is the motor's lack of torque. If I don't shave for two days, the 1775 doesn't have enough power to shave my beard. Braun said it was a bad cutter block and foil and sent me replacements. The results were the same. I have an old Braun travel shaver that has more power than this device.Moreover, the trimmer doesn't pop up beyond the foil allowing the shaving head to interfere with mustache trimming and such.
