Thanks! Gonna look them up right now. How difficult would the prompts be for an English only reader?
Not bad as I speak no Chinese. The only thing you need to know is the pairing uses the standard hold the power button until the led flashes alternating blue/red and then it pairs without anything special. When the power is nearly out it starts with an audible message at about 1 minute intervals. I've had no issues using mine although I admit I have no clue what the female voice is saying, what it is telling me has been pretty easily discerned.
