The weight of the Holy Stone is about 14.1 ounces and a dimension of 12 x 12 inches. The range of the transmitter is 330 feet, with the ability to stay up to seven or ten minutes of in air at a go. Despite the weight, it is still in line with the FAA’s regulations, and you will not require a license. The drone has a slow rotation around the vertical axis, i.e., yawn, although you will still do some tricks conveniently with it. The resolution of the photos taken by the drone is not so bad. However, there is reduced stabilization during flight times. 
HD video starts at the resolution of 1080p as a minimum. For all of these drones, the video is captured at the lower resolution of 720p, even when they claim to have HD cameras. The resolution of still images is always higher than the video. With still photos, the resolution can be as low as 1 megapixel (equal to 1000p) and that resolution is considered HD for still photos. 
Since repairs are as easy as soldering a couple motors and the flight controller has proven reliable and capable, people have developed a few nice modifications for it. Modifications such as a chassis swap with lighter and more durable materials are fairly easy, even for those without electronics skills, and yield longer flight times as well as further improved handling.
As one of the fastest growing hobbies among tech buffs, photographers, and enthusiasts alike, drones offer a unique experience unlike any seen before in the world of hobbies. I remember when I was younger, one of the coolest things to do was to go down to the hobby store, buy a model rocket, and shoot it off in a field down the road. Now there are drones with cameras that can flip, swoop, and record video. On top of all that, they are even available affordably under $100 price point.
Although this HD Drone can be flown safely outside, make sure to avoid too much wind whenever possible. This is a lightweight drone, and as such it is susceptible to harsher weather conditions than some of the heavier, higher end drones. For hobbyists just itching to go out on blustery days when the wind is howling, try leaving the drone at home and taking a kite out instead.
If you are a beginner just learning to fly with these cheaper drones, take your time to learn the controls by flying in a safe area that is a wide open space, with no wind, and no obstacles. At first, fly low to the ground until you can maneuver your drone correctly. Practice flying on a single battery charge and then let the drone cool down for ten minutes before flying more.
