It looks good at a good price, if you just want the leg I wouldn't worry, the whole arm I would do some low level first and check the log as the motor is the only part that a copy could mess up if it is a copy, but that goes for any critical part from an unknown source
Yes I get that completely but I only wanted the leg so I have no need to check anything further but the rest does look too perfect to be a copy but what do I know? I'm happy with just the leg as I mentioned but I do wonder if there even is such a thing as a "copy" at this moment in time without sounding naive as I am very aware of generic items & nothing annoys me more than false advertising (You really have to do your research to get good battries & media type things on eBay etc) but are there fake mavic items even out there at the minute apart from the obvious (that do not claim to be oem anyway) bits
