I have an Air 2S. This shell is very tight. There is no room for manoeuvre. The charging slot, as shown in the promotional image, is really useless. I had to cut it slightly larger to fit the extra battery (see photo). Baffles, especially in the drone bay, are incorrectly installed and 1 propeller is bent. I had to cut the spacers to fit. Basically fine. It fits in the top compartment of my 20L Peak Design Everyday Carry backpack. Won't buy again and recommend other Air 2S to look elsewhere.
