We travel a lot and have had GE almost since it's inception. For us it is MORE THAN WORTH the effort.

We almost always travel only with carry-on and since having GE it usually takes us less than 7 minutes from the time we arrive at the GE kiosk until we are leaving the Customs Hall - the bulk of that time is spent walking from the Kiosk and to the exit. Of course, on those occasions when we have checked bags we have to wait for them to arrive at the carrousel but once we claim our luggage we are on the move again.

By the way, there isn't much "effort" involved in getting GE- you fill out an application then upon approval you schedule an in person interview with CBP. It took us 30 minutes to drive to the airport for our interview and the interview itself took about 15 minutes - all very easy.
