A recent on water comparison of new tubes pro claimed the Barf Ball to be "Probably the most creative tube we've ever seen" and "You just have to see this one to believe it. The star of the show." The Barf Ball is incredibly fun to ride, the soft sphere makes the ride very smooth if you want it, but with the round shape and your ability to shift your body around inside the tube, you can be spinning in no time!
