This is a perfect case for my RG Cube XX! The handheld fits inside precisely with just enough room for you to get a hold of it to get it back out again. The elastic strap keeps it from falling out, and there's even a small storage mesh in the top. There's one missed opportunity here: the space in the bottom of the case between the two handle/bumps could have been open to store a USB cable or charger, which would have been nice.
