The device is easy to handle. As with the equipment of some other manufacturers need only insert the test strip and the unit turns on automatically positioned. Then, of course, apply blood drops and you start the measurement, which provides after 5 seconds the result. I conducted several comparisons with other instruments by such. As the Contour from Bayer. The deviations move in space of + - 5-10%, sometimes the results were identical. Who must pay the test strip, runs particularly favorable with this product because of the test strip from other manufacturers you pay about three times as much. From me a strong buy recommendation.
