When opening the carton, missing the presence sensor of the bag support. I wanted to get that element (which must weigh 10g), rather than return the vacuum cleaner (6kg). After sending one email, I was contacted very quickly by Amazon, which offered me a full refund after returning (free) + 1 complete product voucher worth 10 as compensation. Commercially, no complaints; so I put 4 *. However, it seems that the word "Amazon - Reconditioned Offers ensures the same quality of service as Amazon.com" is not entirely justified, since exchange (the same price) is not possible. Since the order, the price of the repackaged product increased by 16 (nine and 32!) and if I order another one, I'm not sure he did not miss an element ... Anyway, I'll probably keep the aspi which, at first glance, seems to work without the detector. Excerpt from email received "stocks reconditioned offers are constantly changing, it is unfortunately not possible to replace an item purchased from reconditioned offers. However, you can always return items within 30 days receipt of it and receive full reimbursement. "
