It also has a few warm-up exercises to use with the Xertube. Overall the product seems well made and should be a good addition to my son's warm-up routine. Just a little note of caution . . . I happen to use this item and accidentally touched the powder that is on the rubber tube and then rubbed my eyes. It will irritate your eyes! Not the product's fault just a warning. Oops.
