FANDRAGON USB Wireless Gaming Controller

I bought this controller to play flight sims on my PC since my wired 360 controller stopped working. I hadn't had issues when buying other (admittedly simpler) types of electronics from no-name brands on here. And this one...well, technically it works. But that's as much praise as I'm willing to give. The right stick will often act up for no reason, something which seems to be solvable only by taking the batteries out (and not always then). It will randomly decide that the batteries are dead, sometimes when there's three quarters of a charge or so left, but you can take them out and put them back in and it's none the wiser. The battery cover has a mind of its own, and will literally fall off even when the controller is upside down. Even so, it's very easy to set up, hasn't actually broken irreparably yet, and works well enough as a controller when it's in the mood. But I feel like my ability to tolerate this thing's (many) faults chiefly comes down to the fact that I can at least pause from the keyboard, do whatever I need to do, and then unpause; I wouldn't dare use this in situations where this wasn't possible (say, an online game where pausing doesn't really pause anything, or a console where there's no keyboard). (And I would say that 10-20 percent of my gaming sessions end not because I want them to, but because this thing does.) All of the above having been said, while it works well enough (perhaps I should say fails infrequently enough) that I can't really justify spending yet more money on a better replacement, I would under no circumstances buy this again if I had a do-over. If you have any love for yourself, spend that bit more and get a controller that won't keep you guessing like this one. Edit, five days later: I officially give up on this thing. I just bought a fifteen-dollar Logitech wired gamepad and as soon as I get the notification it's delivered, this is going in the bin.
