So sorry I bought this.  I am seeing in others’ reviews the problem with the safety lock.  The piece attached to the bowl that is to activate the lock is not long enough to activate the lock and allow the unit to turn on.  Like others, I used a knife to press the lock, and what do you know?  The unit turned on!  I have worked with this so many frustrating times!  Too bad the bowl has to be attached to actually work!
