Hi there, the main reason for the IFI Audio 7 days Money Back Guarantee is to allow you to bring the product back home to try with your own rig, your favourite music and up to 7 days to access if it will improve your current rig. Now assume if it does, you are happy and we are happy for you. If it doesn't make any/much difference, or if you think it not worth the price for the differences, Just return back to us as per the T&Cs stated in our website for a FULL cash refund. No questions asked. Absolutely no risk on your part. Hope this helps.
