the quality is top notch, but the manual I found inconmprehensible. There's no diagrams and no examples of how to do anything, instead there's geeky explanations that are too abstract and not practical. Instead, I checked the manual for a Joyo switcher (it works the same for the Harley Benton Fxl Pro) and it was all very clear, with step by step examples. I now have the Harley Benton Fxl Pro, which is what I am using now, and am very happy with it, the quality is similar and the price is even lower.
