The price for this little drone is only about $30. It’s one of the cheapest quadcopters you can buy (but cheap isn’t necessarily a good thing). It’s very fast for how small it is, but at the same time since the rotors are so small and close together, people have found that it’s a bit hard to do bank turns with it. Since the Proto X is so cheap, there is a chance that you could buy a defective one, but you can always just send it back.
The Phantom 4 Pro is an excellent choice for aerial photographers that seek professional results. It features a 1-inch CMOS sensor and shoots 4K 60fps video, making it great for filmmaking and photography. It also features DJI’s FlightAutonomy system, providing you with five directions of obstacle sensing. This can come in handy when flying in tight spaces, which is sometimes required for filming and photography. If this feature isn’t hugely important to you, you can save some money and get a Phantom 4 Advanced, which comes with two directions of obstacle sensing. While this drone model is no longer in production, you can pick up a refurbished one! 
These drones for sale are great for all levels of drone expertise because of the Absolute Control mode to change the experience level and is instantly stabilized from its design once in the air. You can even unlock community achievements through your altitude, speeds, and time records. The battery life is a whopping 12 minutes, which is great considering it’s still considered a toy drone.
The JJRC H26WM is a great drone for beginners or those who want a casual drone to zip around with. The camera is pretty decent but nothing too fancy, so don’t expect the world from it. The maximum amount of flight time you can get is approximately 7 minutes, so having an extra battery is a good idea. The camera allows for 2MP in FPV which swings around in all directions.
There’s only one thing that the Parrot Mambo has that you won’t find on the Tello. Legos. Although DJI shows Lego blocks in their advertising photos, the Tello is not Lego block compatible like the Mambo is. For adults, this isn’t something you should care about, but if you’re buying the Tello for a kid who likes Lego, you might want to consider the Mambo instead.
Pairing the remote with the drone is quite simple and works well. Like many other toy drones it has a 360° ROLL-OVER feature so even if you’re not a stunt flyer, your friends will think you are. It has two bright LED lights, one red and one blue which makes seeing it at night much easier. This quad comes with a spare set of blades which makes it great for giving as a gift to a small child who has never flown one before.
