At this time I am a relative newbie with drone flying. It was a bit of a process to sort out all the different options on product, configurations (base unit vs. Fly More Combo vs. non-DJI combos) and useful accessories. Hopefully, my experience will help others making the same decisions I faced.A great deal of what can be done with a drone like the Air is dependent upon software like the DJI Go 4 and third party software like Litchi (https://amzn.to/2F9Xza2). If you are going to get a product like the Mavic Air, you will find there is a lot to learn (for safe and responsible flying), and that the technology/features of the drone make it a good experience when flying.I'll offer some thoughts:* If you're going to get the Mavic Air, you should opt for the Fly More Combo option, as opposed to the bare bones unit. You will want to have the extra batteries. My suggestion is to avoid purchasing any third party batteries other than DJA. Similarly, stick with the propellers from DJI.* On Amazon, you will find many combo offerings with the Mavic Air from different vendors. Just stay with the Fly More Combo (make sure it is item model number CP.PT.00000165.01).* Although many vendors on Amazon offer the Fly More Combo, this vendor (https://amzn.to/2FaBXu2) was one of the few that had offered it at a significantly lower price [suggested retail is $999, most vendors on Amazon charge very close to $900, and this was one of the few vendors that had a price of $842]. I never ordered from this vendor before. I read the reviews. Once of the factors in purchasing from this vendor over similarly priced ones is that the orders are fulfilled from Amazon. Whichever product you choose, look for the link on the page that says "Used and New" which identify the various specific vendors. The one I purchased from had "Fulfillment by Amazon". That way, if there was a problem with the purchase, I could deal directly with Amazon Customer Service.* When you get your drone, at the time you register an account on DJI, I suggest you opt for the "Refresh" servicing plan that DJI offers. I believe its $89 and covers a 3 year period. Apparently, you will have to opt for it within a 48 hour period of when you first register your product.* The one drawback on the Fly More Combo product is that it has two cases- one for the drone by itself and another for everything else. That in itself is not a big deal, but the nicely made larger carrying case for everything else but the drone is clumsy to unpack and repack the batteries, charger, remote control, spare propellers, and cables. This would be a mess if I were to venture out into the field with this. A more practical option was to get a case designed for the Fly More Combo. The one I chose is a hardcase made by Smatree (https://amzn.to/2FaKXPU). It comfortably fits everything (including an iPad Mini to use with the Remote Controller) but the propeller guards and the international AC adapter (the AC Charger comes with both a regular 120 volt plug for the US, and also a 240 volt adapter which is standard throughout Europe). The propeller guards are good for indoor use, so it may not be an essential piece to take with you when you're out and about.* Happily, the remote controller works with both Android and IOS (phones and iPad Mini). I like using the iPad Mini with the RC, because the screen is not tiny, while the combined Remote Control/iPad is easy to handle. If you are going to use the iPad Mini, there's just one slight frustration - it requires an extra cable having a lightning connector on one end with a micro-usb connector on the other end. I had to do a little searching on Amazon. The one I found is: https://amzn.to/2Fabvko and I am sure there are others you'll find on Amazon (roughly about $8).* One last thing... As the Mavic Air is over 0.55 lbs, don't forget to register the device with the FAA.Apologies for the lengthy review. Houpelly there's some useful information here to make a more informed purchase.
