This is my second Weber Q grill.  It's a perfect size for 1 or 2 people, with enough room to cook for a group on occasion.  My first grill lasted about 15 years - I'm assuming the next one will last just as long.  The only real difference I have noticed between the old and new models is that grill surface used to be one piece, now it's 2 pieces.   Have to be a little careful putting things in the middle where the 2 pieces meet.
