Great protection and 100% Build quality that you expect from Peli. This is a product that will last and survive rough treatment. The clear lid allows you to see the contents without having to open the box (even better for the type of environments its designed to be used in!).
Built in secure seal lock, and pressure release valve.
Extreme environment and water proof too, so you can be sure the contents are very well protected.
Pretty much indestructible, the only (minor niggle) is the slight bulk, but the trade off is the very high protection.
Highly recommended, very high quality protection.
