The first impression: Very good! But then the practice. No coupling possible. Now that can happen. Seller informed. Returning and new to come. Good service we thought. Then came the second. No coupling possible! We felt taken from us on the arm! Withdrawn from the contract. As also had more than 3 Euro fee to pay for the ordered goods was broken twice. We leave the Amazon and the lawyers clarify.
Incidentally, in a second provider ordered: Goods arrived as promptly and see. Instant pairing and everything is clear. The Bluetooth headset is highly recommended. But you pay attention to the seller.
