This travel case is just very well designed. With a large size, you can slip a GPS but also other small devices that can travel safely without being crushed by something else in your suitcase or you want to simply put away cleanly. The case is designed so that no device will "crush" the other in either the left side or the right. Personally, I've slipped a GPS, a portable console and a small camera with its power cord without forgetting the cup: all this safely, no device will be damaged. The existence of a zippered pocket can store small accessories that go astray more.
The set is solid and well finished, it's a beautiful product the size of a large book, black and discreet that simply closes with a zipper. Its lightness makes it a very valuable product.
