It's not that it didn't live up to expectations. More like a wish. There is not enough gyroscope so that when tilted, control is transferred to the object. Pros: A worthy gadget, it fits perfectly with a laptop running the 10th Soft windows, both on the blue tooth and on the cable (it's good that I took the device with the usb cord in the kit). Powered by conventional batteries, if you connect it to a computer with a cord, you can do it without them. . With a tablet (firms with the letter "X") under Android, it is also good friends, there I master the popular fighter of our sworn friends. A smartphone with a similar operating system is similar. . I like the controls, while I don’t use especially heavy games, I have fun in a free semi-arcade flying game about the aces of the First World War, downloaded from the application store. I did not find dead zones, the sensitivity of analog levers is decent. It is pleasant to hold in the hands, does not slip. . For shooters, advanced flight simulators and car racing, in my opinion, it is better to take other devices (pistols, gaming mice, joysticks and steering wheels with pedals). Got cons: Doesn't work with iPhone 6 Plus. But I didn't count. I don’t need this smartphone for games, I just tried it using the “head-on” method - it didn’t work out, I didn’t dig into the settings, I didn’t really want to.
