This fluctuates. As we sell new FP2’s there will always be people who use their right to return in the first two weeks. Phones from this so-called ‘cool-off’ period are then shipped back to the factory and checked and then put on the ‘refurbished phones’ stack. Every month we receive the stack here in Holland and we then allocate them to different groups: internally, partners, testers, clients etc. The demand in each of these groups also influences their allocations in the next round.
The reasons are very divers and not always known as people have the right to return anything they buy online to the producer within two weeks without giving a reason. I have no numbers of the amount of cool-offs, but I can check if someone of the support team knows.
