Let me start by saying that they are so bad I wouldn't even risk flying them to try them. They were sent back immediately. Read the full story below. I was looking for an adjustable joystick because I have to pinch the front sight due to nerve damage in my thumb. A higher adjustable joystick would make this easier and more comfortable. That's why I ordered them. Firstly, as you can see from my photos, they are NOT AS IS. Your photo shows a smooth shaft between the grip and the bottom of the joystick. It is not. That's the exact same screw that goes into the controller. The "adjustable" part is just a knob with a lock screw that turns VERY easily and has no LOCKING MECHANISM. To set them up, perform the usual right-to-right/left-down motion to screw/unscrew the joystick into the controller, but with the stick it's the other way around. This means that if you rotate the joystick all the way in (clockwise), each subsequent clockwise rotation loosens the knob. If you already have a handle mounted on top, IT WILL FALL OUT! With your index finger on the shaft or the handle all the way down, any counter-clockwise movement will easily unlock the JOYSTICK! When any of these things happen during a flight maneuver, a myriad of dangerous and embarrassing scenarios can happen. I DO NOT RECOMMEND THESE JOYSTICKS, especially for novice drone pilots who may not be able to adjust quickly if something goes wrong. And the last. Note. The plastic box they come in is pretty flimsy. Mine was most likely crushed during shipping (see photo) as it was packaged in Revain flat plastic packaging rather than a stronger box. To me this wouldn't be a deal killer, but if you plan to use this to store joysticks when not in use, you're out of luck.
