When unpacking shone through the cushion cover (no optimum packaging) an LED that was turned on. The reason was a defective switch that no longer einrastete in the positions ON / OFF, but rather wiggling. But that was also a LEB darker than the other, because the battery had probably taken something in the mail car-duration Interior illumination.
After contact with the seller, I received prompt new glasses - good service. Since the switch a LED were okay but again dark. After replacing the batteries, everything was okay. What a hassle! But only three stars.
