The DR-1 is $19.99 before shipping costs and has no camera, so keep that in mind if you want to film something from the air, as this product can’t do that. However, after a 20-minute charge, you will be able to fly the DR-1 for about 5-8 minutes.
To show you that this is in fact, a real product, here is my confirmation email. It has my personal information removed, but it does show that this product is real.
So if you do want to purchase this mini-drone, OnePlus says it is only available in a “limited quantity”. It could be a great gift for someone you know or you could use it as a stepping stone to get into the hobby of drones.
