The Pro version is worth it. Nice set and storage box. The built-in charger is pretty fast when plugged into a 2A USB power adapter. I used a 1500mah 4S LiPo on an xt60 connection but wasn't very happy with the performance. Fine for travel when you don't have access to USB power, but I don't think I'd fly this little guy into the wild, away from civilization. A few screws rubbed the edge of the dome a little, a quick blade attachment to the edge of the dome fixed that.
