Further, in no event shall the liability of Horizon exceed the 

individual price of the Product on which liability is asserted.

setup or assembly, the user accepts all resulting liability. If you 

as the purchaser or user are not prepared to accept the liability 

associated with the use of the Product, purchaser is advised to 

return the Product immediately in new and unused condition to

to state. Horizon reserves the right to change or modify this 

warranty at any time without notice.
