I typically use them mostly when I ride. I can't eat a Power Bar or anything solid when I'm out riding my Mt. Bike, So I'll suck down a enery gel. Power Gels have saved me on numerous occasions from suffering too much on long rides.
As with enery gels, you need to drink lots of water. I know people who been doubled over with cramps after drinking Red Bull, because they hadn't drank enough water.
My sister who has climbed Mt. McKinley (along with the highest peaks in So. America, and a number of peaks around Nepal) on a number of occasions lives by them. She says that the gels won't freeze when it's below 0F.
