If you are wondering whether 100 bucks can buy you a good drone, it can get you the NEHEME NH760 quadcopter for beginners.
This quadcopter is for adult as well as kid beginners. It is easy to fly, has good features to introduce you to the world of drones. It will give you a good foundation on how drones fly so that you can buy a bigger, better one with higher specs in future.
The NH760 also comes with many flight modes, which make it easy to fly even for kids. It also has a camera, so you will get a good introduction to aerial shooting.
While the drone ticks many boxes, it also has some downsides. For instance, the smartphone holder on the remote controller is not going to hold heavier mobile phones.
Also, this is not a GPS drone, so it lacks the fail-safe features that most other drones in its price range come with.
Apart from those two things and the lack of blade guards, this drone does what is advertised. You will definitely outgrow it soon, but for the time you will have it, you will enjoy using it.
