I must say that I really like the joystick, he makes a robust impression and can be buttery soft and fine control. In addition, there are a lot of buttons that can be programmed as desired. The joystick is also very good in the hand. The calibration problems I can not say anything yet, but I have the joystick is not long enough. My Joystick I bought directly from Amazon, this came with the inscription Rev. 3. Thus, I might assume that Logitech has solved these problems. I'm curious how does my joystick in the future, something should change I will add this.
