This is the reason why I opt to do my own research and product comparison. I'm not here to bash anyone's product, BUT I will say that no one likes poor customer service and it will not improve your reputation nor your costumer base. Bad reviews always travel faster than good ones...
And that's why I'm working on my own controller
My design will be pretty much an universal solution for any sensorless BLDC motors out there from 50 to 500W monsters. Also since it will have serial capabilities it will be easy to integreate with most aquarium controllers. This may not mean much for some, but for those that run multiple pumps this means the ability to have an integral wavemaker!
