DCS' Products are used are appropriate and compatible with those Products. 

If Kele determines that a returned Product does not conform to this warranty it will, at Kele's discretion, either 
repair or replace that Product, and will ship the Product back to Buyer free of charge.  At Kele’s option, Kele may 
choose to refund to Buyer the purchase price for a nonconforming Product instead of repairing or replacing it.
