This thing operates as smoothly and easily as an indoor drone will EVER operate (probably). Our 12 year old & 7 year old grandkids were doing great fun flights after just a few introductory instructions from 73 year old me. Just pair the drone to the controller (move left stick forward then backward) hit the OneTouch button to pop up the drone about five feet in air (keep the rear red light always pointing rearward for easiest operation) then move the drone where you want with the right stick. Use the left stick forward or backwards if you want to raise or lower the drone. Move the left stick Left or Right to rotate the drone clockwise or counter clockwise (to keep the red light pointing in its same starting position.

Try not to change the controller's orientation during the flight. In other words, keep sitting or standing and pointing the controller in the same direction throughout the whole flight - no matter where the drone goes. Hit the OneTouch button again when you are over your landing area. (Best controlled landing you could ask for.)

If you really want to trim the drone (to minimize drift when hovering in place) push straight DOWN on the TOP of the left stick (like you were trying to push the stick INTO the controller) while correcting any drift by moving the right stick as needed to hold the drone in place. Let go of both sticks and see if you are happy with your corrections to the drift.

I have been looking for a mini drone that would essentially fly right out of the box and the Poltensic A20 is that drone!! Charge time, for the internal battery, is about 20 minutes, which is great as you can't swap it out for a fresh one. The included instructions are straight forward and very easy to understand. We unplugged the drone from the charger, followed the easy setup and calibration procedure and pressed the take off button. I didn't even have to set the trim and the drone was hovering fine in my living room! I handed the control to my 7 year old grandson and he was flying like a pro in a matter of minutes. Just what we were looking for!! At this price point, you will absolutely love the simplicity of this drone and how much fun it is to simply fly.

In my opinion this is the PERFECT drone for beginners. Between the altitude hold (hovers by itself) and three speed levels, this thing is a breeze to fly. Flip it into high speed mode and it'll zip around the room like you wouldn't believe. I've also smashed it into plenty of walls and it still flies true. I bought two of these and had a blast teaching my father how to fly in my living room. A lot of fun to fly, you'll definitely get your money out of this little guy

SUMMARY: Durable and has protected propellers which makes it safe to learn on. The altitude hold is a great feature for first time fliers. Perfect for younger kids and adults who are kids at heart.
DETAILED REVIEW:
Flying: With the altitude hold, this quadcopter hovers like the firefly, for which it's named. You will need to make small corrections, but it makes it easy to learn the basics of flying. Try flying figure 8's around obstacles and through the legs of chairs and soon you'll be ready for something more expensive. It has 3 speeds from walking speed to jogging. It beeps to let you know. It is a bit tame for more advanced fliers and it doesn't do flips. I've flown it outside up to 60 ft away and above the height of telephone poles. Understandably it can't handle more than a light breeze. It has automatic motor shut off when it crashes (I crashed on purpose in my video).

Battery: It has a non-removable battery with a tiny plug that is a little tricky. I got 5 ½ minutes indoor flying before the lights started to blink and 7 minutes before it auto-landed. The charger has a small red light on the chord which turns green after about 30-40 minutes of charging.

Design: Made of a very durable rubbery plastic which seems indestructible. The propellers are well protected and they pull off if needed. The frames seem similar but is slightly shorter and wider than other mini copters (F36, H36, E010) but the body seems to have a much more premium construction (see picture). There is a nice white headlight and a red taillight which work well for orienting the front and back. It has a very small on and off switch and plug on the back. Some people may not like that the battery is not easily removable. The charging chord plug is also very small making it hard to tell which side is up and down but it is not a big deal.

Controller: It is small but easy to use and quality far superior to those on other mini copters. The control pads are a bit stiff at first but great once they break in. It takes 3 AAA batteries (not included).

My Tips: Periodically take off the propellers to remove dust bunnies which can build up inside. Remember to put them back in the right spot. There are 2 different props. Diagonal props are the same. Keep the box it is compact and nice quality. It can be used to transport it. Altitude hold seems to work better if it is manually launched (pull both sticks down and in) rather than using auto take off. If you have a hard crash you might want to shut it off and restart it because the gyros can get confused.

The Company & Quality: Mine did not work in headless mode and it had altitude hold problems. When I opened up the controller it looked like a bad solder on the circuit board. These toy copters often share stock parts and are prone to quality glitches so I don't hold it against them. I contacted Potensic and their customer service was great. They were helpful in customer support and were willing to stand behind their product. The new one is perfect.

Other Options: The H36/F36/E010 are much harder to fly without altitude hold and they don't seem as good in quality. There are similar models with cameras but that will drain batteries and cost more.

Bought it as a gift. The kids played with it and it seemed to perform as expected. They had fun and at the end of the night it left with the birthday boy. He is a rough kid so I can only imagine once he got home he destroyed it ;-) no fault of the product. From my day of observation all were happy and it worked as expected. Seemed easy for them. One of the boys did knock it out of the air with a pillow. I powered off and on and once again she flew like a bird!
