I have been given at the clinic the unit. There were also comparative measurements carried out with a professional device. The Nano has reached the professional device less than 10% tolerance. Thus one can say, it measures very precisely. In the supplied bag is enough space for test strips, lancets, a lancing device and small items. The device is mounted in the pocket, it must not be removed for measuring. This easy and fast measuring is possible. For each measured value can be specified whether it is related to a meal or not. It is thus possible even in the device a statistic to lead.
In addition, even a voucher for a larger bag was included, in which then also an insulin pen has room.
All in all a very good device for diabetics everyday.
I have however withdrawn, because the test strips are very expensive one star. There are quite comparable instruments also their consumables to 2/3 cheaper.
