My KS E90 arrived today c: and just figuring all the hings out for it was a pain, loading the magazine was deceptive and the instructions only told me how to load high capacity magazines, which I don't have. Then getting the battery wasn't too easy either because I didn't notice you had to push the cords into a certain spot. But I like it so far, I need to buy more BB's and get batteries for the red dot sight I got and I'll be set.
