Overall, this is a quality case. Whether it fits your device well is entirely up to whether your device dimensions fit the dimensions of the case well. There is no foam padding inside, but it has a nice one inch wide elastic strap that runs the length that holds the device fairly well. But without foam, it will not have much shock resistance if you want to throw it around. But you do gain a slim case without a lot of foam padding. The shell is quite firm, not foam, and seems to protect very well. The top is reinforced and is stronger than the bottom half, so I would orient any LCD screens face up. Like any case, the weak point is if compressed in the center you can flex in if you squeeze it. But it seems significantly stronger than foam or some cheaper alternatives. It would have been nice if the bottom was reinforced as much as the top, but the bottom is still quite firm, just not as resistant to compression. I just wouldn't this at the bottom of a suitcase.
The outside dimensions are 6" wide, 4" long, 1.25 " thick, with rounded corners. Inside dimensions are 5.25" wide, 3.25" long, with rounded corners. My
Western Digital My Passport Essential 500 GB Portable HD (measures 4.3" x 3.25" x 0.5") fit easily with room to spare width-wise and in thickness. The strap held it in place well thickness wise and fairly well length wise where there were gaps, but you could still shake it end to end if you tried. It was more than enough for tossing in my laptop bag and toting with me. Just for some versatility and other dimensions that might fit, my
Magellan RoadMate 3065 4.7-Inch GPS (5.375" x 3.312" x 0.625") just fit with being able to zipper around it without forcing it, but was tight. I would definitely orient my Magellan LCD screen up for better protection. It might be a bit tight for shock absorption, but seemed okay for tossing in a glove compartment or purse.
There is a netted section on the top half to hold accessories with another fairly strong elastic band 0.375" thick and held about 0.25" from the back. You are probably pretty limited to fit something small with your device in here. Maybe you could put a small USB cable or something. But you could also be adding a pressure point that if compressed from outside would transfer to your device through the object held here. I suppose you could put your own piece of foam here for added protection, but it seem unnecessary.
