Peli 1535 Air TrekPak Black

Almost perfect, because of the wheels - they are very well made and will probably last forever BUT, on this model, you can't change them as they are part of the whole plastic part that is in the back. On some other and older case models, wheels were separate units.
Why change them? They are extremely loud when you roll the case outside and it draws attention, which you don't want if you have expensive equipment inside. Otherwise, it's very well made product, perfect size and amazing Peli quality.
