This controller has a zero start function built in. The delay in the throttle response is flat out dangerous. I've hooked up other controllers no problem, this one is a nope.
Got full sized adult man hands. Works amazing. If thumb is too weak, or your hands too small, get a second person to press up where the charger port is.
Being an adult, this feels as ergonomic as i can imagine it getting. Very comfortable and helpful for use with arthritis or inflammatory joint pain in the hands or wrists.
