Apparently they are prone to flutter, but properly designed give 5% drag improvement at cruise.
Not to be sniffed at - even if less greenhouse gas doesn't excite you, dollars in the pocket should.

Correct.
Retro fitting winglets to the 767 provided an increase in fuel efficiency of over 6%. Certainly not to be sneered at in these price conscious times. Changed the flight dynamics too with much higher climb and descent speeds.

It certainly does for early design wings. You will notice that later aircraft don't have them- B777 onwards.
