On a cross-country bike trip this summer, I tried just about every energy supplement that's out there (gels, bars, blocks, drinks) and I would have to say that the shot bloks are my favorite. All the flavors taste great (except for the lemon-lime one, I think) and they have saved me from bonking multiple times. The only problem I've found is that a serving size is 3 blocks and the package holds 6 blocks...it's not the easiest to close the package back up after you've ripped it open while out on the road.
A good product for use during a game and as an alternative to GU, I use both and use them interchangeably. Need to drink water with them as they are like eating gumdrops in consistency.
Taste good.
This is a nice diversion from PowerBars or Gu's.
There is really no way to carry them during runs so I eat them before or after workouts.
