The Accu Check Aviva Nano is nice handy because it is smaller, but that's it. The device has a high power consumption, and it will be needed again 2 button cells. For me the device went on power or use the test strips often in the setup mode, so that you could not measure. Until the device is ready back had (power cycle) could also again "re-pierce" for blood collection. The bugged permanently easily. Apparently the device is seen electronically probably too sensitive.
Now I like the normal Accu Chek Aviva, which is always reliable and the button cell (he needs only one) many times last longer.
