Purchased from the Orange Box store for $30.00.
Purchased foam from the same store for $4.00.
Transmitter fits in the center area, while charging cables, balance equipment, and testers fit nicely in either side. Everything inside the case is removable, user is not required to use the storage trays or dividers.
Weather resistant. Lockable. Stackable. Durable, yet lightweight.
Worth every penny.
I use the entire "system" for all my gear and love it. Nothing gets lost, electronics stay safe and dry.
Good luck!
