Review on CASEMATIX Waterproof 15.6 inch Laptop Hard Case - Ultimate Protection for Acer Nitro 5, HP Pavillion 360, Lenovo Flex and More by Michael Nard

I bought this before a trip and was really blown away by the durability and reliability. I wanted to test the water resistance so I opened the case on the plane only to open it again off the plane and I can easily say you don't have to worry about water. I couldn't open the case with a metal object until I opened the exhaust valve. The seal is secure and you can rest assured that everything inside is secure. I wish the design was better. It hurts a little, but works great.
