I love all ZWO products. None of them have let me down yet. My only complaint is the quality of information/training available for any product. As an example here, neither their manual nor any reviewer mentioned that the zero position is initially the position when you turn it on, but then zero may change to a specific sky position after the first plate solve. It is intended to provide rotational references specific to sky position. It's a great way to do it, but not what was expected and no where was it explained. Other brand's equipment is worse in terms of use information, so in comparison, ZWO is the best. The unit itself is incredibly well made, easy to install and works as stated. It's thin, short profile is perfect for any rig.
