As a sound engineer I come across Peli cases all the time, being thrown in trucks and generally abused. They are pretty much indestructible. The 1510 is designed to be the maximum dimensions of carry-on luggage, and will last a lifetime or more. The advantage of having an orange one is being able to spot your stuff from across a darkened room. The wheels and handle mean you can get your tools back and forth from trucks, hotels and aeroplanes without burning yourself out. Enough space for laptops, mics, interfaces, tools. The case you will see being wheeled alongside working professionals.
