I picked up a Mavic Pro 1 for $600 on eBay a few weeks ago. Turns out it was a refurbished unit, which isn’t a big deal to me, everything works perfectly. Wondering if it’s worth doing the video showing everything working as instructed by DJI and send it in to be approved for DJI Care Refresh, has anyone done it on a drone bought second hand ? I’m a fairly experienced pilot, you just never know what could happen.
