3.0 out of 5 stars Good first quadcopter for a drone newbie, but I got a dud
By Daniel Diaz on December 29, 2015
For $20, is pretty good, but not great in general. I like how it has the ability to do flips and has a prop guard that works good enough. I was a bit surprised at how small the controller was. Did not last very long though, I had done a couple crash landings on grass from a few feet... which was nothing that could damage this, apart from maybe getting some dead grass on it. Anyway, it was my third time flying it and I was still learning how to control it well until it just went crazy and pulled hard to one side, almost crashing into a wall at a high speed. I killed the throttle and let it drop to the grass to see what had happened. Battery was not dead on neither the controller or quadcopter itself. Propellers were fine and not bent or broken. Gave it a little bit of throttle and all but one propeller functioned. One motor must had died mid-flight or a cable broke or something, all I know is one motor will not spin anymore, rendering the whole quadcopter useless to try to fly.

Battery takes about 25 minutes to charge from a 2.1 Amp USB charging port, but will take longer from a low amp port from something like a computer, some wall adapters, standard car USB ports. Battery lasts probably 7 minutes total, but if you keep having to get the quadcopter and relaunch, you can get maybe 15 minutes or more with it. Battery in the controller lasts a few flights. The two batteries are the same, one for the quad and another for the controller. Both removable and you have to charge one at a time unless you buy a special charging hub. I suggest you buy more batteries and a hub, like the one I linked below.

Comes with two extra green and two extra black propellers and a tool to remove them. A manual is also included. Nothing else.

My verdict:
If you are on the fence, get this. I was just unlucky and got a bad item, but the quad itself is pretty good for how cheap it is. This is one of the few $20 quadcopter/drones that has a full propeller guard and does flips in any direction. I would say this is the best out of those few. This is something great for children, as your first quadcopter, or just to entertain yourself with. If you are more experienced, get something better like a Syma X5C-1 for $50, which is what I am getting after I return this. Do not eve think about attaching anything else to this, like a gopro camera, it is way too weak to carry anything, but it is quite powerful for itself.

I've included several pictures showing the items included, how one propeller does not spin while the others do, and showing how the wires are still soldered onto the mainboard.
