Yet another modern, inferior product!  Lets start!   It does NOT shut off, or lift the lid by itself, AND You can only let the can go around ONE TIME in the opener Because  IF it does goes around more then once,  there could be possible "metal shaving" being distributed.    Now, you CANNOT see when the lid is fully opened... Its hidden very well, so having it go around more then once is easy to do!  The direction say the best way to tell it has gone around one time is to listen to the motor. When you 'hear a higher pitch"  the can has gone around once &  is open!  WHAT? Listen to the motor?  You've got to be kidding!  This is almost like a Saturday Night Live skit!  I'm returning this!
