Hello, I bought this case for professional use, in fact I regularly take the plane and I needed a robust and waterproof case to protect my equipment. In the first flight, the box arrived completely split on one side without any apparent shock. It is sold for that (expected strength to fly) and is guaranteed by the manufacturer. It asks me to go through Amazon to replace the gold Amazon site said that there is no exchange possible ... I still returned, it's less than the 30d I 'I bought it, I hope it's just a manufacturing defect .. and be able to quickly obtain a replacement.
