I got the Hermitshell from Amazon as well. I can verify that it's a very well-designed, well-made case. Should I take the Tello traveling, I can put it in this case and jam it in my suitcase without worrying about whether or not it'll get crushed. No, it doesn't have a spot for a controller, but there is a mesh pocket for cables or something else, and 4 spots for batteries, if Ryze ever starts shipping them.
I have that one, but it is already getting a bit crowded with Mi2 Extender, battery, and iPhone sunshade.
