Guaranteed...period. Our Replacement Program gives you the peace of mind that if our products fail under normal-use circumstances, we will repair or replace the item at absolutely no cost to you - We'll even pay for the return shipping. This guarantee is for LIFE! Unfortunately we cannot warranty wear and tear due to normal use, nor can we cover acts of dumbassery. But, pretty much everything else is covered. Please see our "No BS Lifetime Warranty" for details.
