Nobody should be buying any more Autel drones due to their limited useful life. Have two EVO 1 drones, but now junk due to lack of battery replacements. They are excellent drones and have never had a problem with either one. They make the best drones available, but they design in a very short life usage. Thought a Nano lite+ would be a nice addition to my fleet, but in reflection, why spend a thousand bucks on a device with such a limited useful life? Unless Autel gets on the ball and gets replacement batteries available for all it's models, buying another from Autel drones is an expensive waste of time. Surely many other fans of these drones must feel like I do. I call on everyone who knows these are excellent drones but come with an Achilles Heel,to demand replacement batteries be made available before they buy another drone. No doubt Autel will remain quiet on this very poor marketing strategy.
