The delivery includes everything, what you need: meter, lancing device, 10 lancets and 10 gauges. I bought because my doctor diagnosed with type 2 diabetes me the device. The device always showed me at normal levels. So I wondered if maybe the laboratory values were confused by the doctor. Wrote my problem the company Beurer and received relatively quickly a replacement unit. The replacement device then showed values that were laboratory values closer, but were still lower. My doctor advised me to an instrument from another company. Have bought the recommended device. The recommended device has actually delivered the most accurate values. The deviation from the exchange device of Beurer was a maximum of 10 mg / dL below. Thus, the replacement device is of the measured values also produces fine. I prefer 2 star off because the measurement results from the first device completely off the mark, and the replacement unit is still less accurate than the other device.
