Looks nice, but accuracy performance is seriously lacking. When a USB device load is applied, the internal voltage loss is substantial. With a load of about 400 ma, the voltage loss gives an output voltage of less than 4 volts, with an input of 5 volts! Maybe if you only draw about 20 ma, it might not have too much loss. If I had known this, I would not of ordered it.
