I have to see one in real life not a trade show not on you tube to see it's full potential yes I agree it does look cool and open to the customer, but if it doesn't clean very good then you have a problem it needs to have the flex coupler arm like Sonny's has on the rear brushes of the I5 to contour to the vehicle many European in-bay washes have it why can't that simple add-on be on U.S in-bays?
