Allow me to talk you out of it. As I PM'd you or commented when you posted this, I bit and placed an order the week of the posting of your thread.
Gearfun is not surprisingly a total fraud.
I bought two drones, and spare parts, and extra batteries.
The company immediately confirmed the sale, sent emails, but at no point stated a promised delivery date. Finally after a month, I emailed the company and asked what the target would be. No response.
Finally, about six weeks after the order, a package appeared on my front porch, with two boxes inside, one damaged from being inadequately packaged. It was simply in a Tyvek envelope with two different sized boxes enclosed.
The return address was in California, but the shipment has originated in China.
Upon opening the boxes, the drones were much smaller than they appeared on the web site. Although, caveat emptor, the website never gave dimensions.
Additionally, the web site explicitly stated the camera was on a dual-axis gimbal, but it was in reality just a slide in bracket with no ability to move the camera in any manner from a fixed mount.
The camera was so cheaply made it looked like it was from a box of cereal.
The drones were not at all what was in the photographs on the web page. The propellers were flimsy and small whereas the pictures showed them capped with hubs.
There were several falsities in the sale. The advertisement claimed they were comparable to $1,000 models from other companies. They were not, nor did I believe that comparison when I bought them, but expected them to be in the value range of the purchase price, in the $100 range apiece.
In actuality, they were the cheapest ones made in the industry, along the lines of the toys sold for $10 at the dollar store at Christmas.
So, I immediately contacted the company, both to the email address they had contacted me from at the sale, and on the company's web site. Despite florid claims of responsiveness on their web page, nothing.
I placed a claim in Paypal for the full amount. Paypal requires the buyer to contact the seller and allows a three day response time. At the very end of three days, a form letter reply came via the seller expressing concern and asking for photographs of the items. The response completely ignored the statements made by me that they shipped an item they did not list on their web page. I stated as much to Paypal and opined that it might even be possible that the seller did not speak English.
Paypal contacted them once or twice, but never shared what responses they received if any. Paypal refunded my purchase in full the next day.
I have never heard back from the seller. I have two drones so cheap I cannot even use them as gifts.
Don't do it.
