They're pretty cheap, only good enough for 5 days of daily use. I use them as an emergency. You need to buy 2-3 pieces. Accuracy, good with a meter on ohms: probes show 2.3 ohms, wires ring and go as low as 0.05 ohms. You get what you pay for here. You need to attach the wires from the package to the plastic probe. No calibration of hospital equipment with these puppies.
