I had the case from them for my Air 2S... I had to glue in a velcro strap to keep the DJI RC in place. As I said, the only reason I use it is because it's slim enough to fit into my backpack I take to work (so it's easy to always have it on me)...
Yes, and I don't really like it, except it's small enough to fit in my work backpack so I can carry it with me.
What I don't like is that the strap that goes over the charging hub and controller is way too loose, so if the case gets bopped...
