I had been an Accu Check. Unfortunately overdo it with the test strips massive and so am I AZF looking for an alternative. This device is not, much too cumbersome to handle and prone to error. In the first use I alone consumes 5 strips until I knew exactly how the drop of blood to the strip. Still, I do not tremble, but who will be unable to operate this unit has no steady hand. Also I fiddle with several portions of rum is bad. Only the trigger, then the test strip, then pack everything again, there is cumbersome. A Manke, no standard batteries but button cells. Altogether too fummelieg.
