Two hands have been killed so far, one of 15-20 foot deaths due to failed soldering on the ESC, the other of 12-15 feet due to elasticity in the Carry Hero 7 (good extra weight). Overall solid enough for me for the price and there are interchangeable levers which I like. It flies great, it has a lot of flight time. Easy to assemble, this is a bottom deck so don't expect to stack even two things on top of each other with the standard 4-5mm spacing - this is easily solved with stacked spacers. However, there are also mounting holes on the back, so with good planning you can mount whatever you need.
