Good
Not too bad. Don't expect miracles from it, worst case voltage was out about 5% on mine, current about 10%.
It has tuning pots to calibrate the values but they max out before you reach the correct values, and even then the error fluctuates depending on the voltage/current, so it might be correct at one voltage/current and then wrong again at another voltage/current. Good enough for something like a lead acid battery
