It says you can open the package and examine the product.
Providing you restore it back to new after use nobody will know if you've used it or not if you decide to take it back.
It can't be that hard to keep it pristine for 14 days.
Andy 91 is correct. No returns to Currys once you turn the thing on (unless it is faulty). Apple have a no quibble return policy. That's worth a lot.
