Thought the idea of the lancing device and the measuring device to plug into a device would not be bad in itself and that's why the device was bought. Unfortunately, then after some time out which measures the unit unfortunately very unreliable. Successively taken 3 values directly on the same finger and deviations of up to 100mg / dl. The device itself is easy to use, defects me not noticed by the operator forth. Alone the unreliable measurements are an exclusion criterion for me. Expiration date of the test strips was far from being reached so I can rule out the cause of the fault. Just think of me also not lag, do it not for the first time.
