Use of the "Go Green" Bead is voluntary and the user is making a conscious choice to place the bead into their gas tank. Though all gas tanks have a screen system to prevent any obstruction or congesting by objects that may make their way into the gas tank, it is the users responsibility to know that their gas tank does in fact have this safeguard still in place. The user understands that the use of the "Go Green" Bead is voluntary and accepts that the seller takes on no responsibility for either perceived or real challenges that may coincide with the use of the "Go Green" Bead.
