I bought my Glo via Whitcoulls online store, where their returns policy states that "Whitcoulls will Refund any defective item ..." which I took to mean I wouldn't have to accept a repair or replacement but could just get my money back if there was anything wrong with it. I would consider myself mislead by false advertising if that was not the case.
