Bought 2 of the bind and flys and 2 of the V3 flight controllers separately. Flying these out of the box is really fun, they fly amazingly well and have a lot of really nice features. After the first board died I figured it was just bad luck, but after buying 3 more I've had the same or similar experience with all three:
First one VTX fried after 3 weeks, second one the U.fl connector ripped off the board and trying to repair it made it worse. Third one the SPI receiver decided to just die on me one day, and the fourth is still semi-working but has intermittent power issues.
Support did give me a 50% off code for one of the boards, but other than that it has been pretty much sorry tough luck - you must have done something, etc (fair enough, I know it's hard to warranty).
There is a problem with AIO whoops boards in general having durability issues, but I think if I'm going to pay $100+ for a FC I want to have some kind of faith that it will last a while. It's also really frustrating to have different camera/motor plugs than literally everyone else in the industry - it's not a good look for anyone in the FPV game.
Bottom line is: I do love the flight characteristics and feature set but I just can't keep throwing money at it and watching the paperweights pile up.
