Do not buy the Waring Duet! mine would not grate or chop well at all and the food processor part is useless - resorted to my tiny Braun handheld which did a better job.
The blender was marginally better though vey difficult to clean. after six months I sent the product back to manufacturers to be fixed. They replaced the motor for free but implied I was using it incorrectly. I finally had enough when blending lentil soup the other day (hardly difficult) the motor burnt out again. It is now in the bin and I am looking forward to buying a Magimix!
