and warrants to the original purchaser that this product is free from defects in materials and workmanship for the 

period of 90 days from the date of purchase. This warranty does not apply to damage due directly or indirectly, 

to misuse, abuse, negligence or accidents, repairs or alterations outside our facilities, criminal activity, improper

to persons or property, or for incidental, contingent, special or consequential damages arising from the use of

If our inspection verifies the defect, we will either repair or replace the product at our election or we may 

elect to refund the purchase price if we cannot readily and quickly provide you with a replacement. We will 

return repaired products at our expense, but if we determine there is no defect, or that the defect resulted 

from causes not within the scope of our warranty, then you must bear the cost of returning the product.
This warranty gives you specific legal rights and you may also have other rights which vary from state to state.
