Poca durabilidad de las pilas, a la larga sólo se puede usar con el cable y es demasiado corto

### ⭐⭐ Review
*by I***S on 2 January 2026*

Data logging on the device does not work. There seems to be a bug in the internal memory storage and the datafile from each day only contains half of the measurements. This means that over 1 year period, only 6 months worth of measurements can be downloaded (despite downloading data from 365 files). Also, having to download each day one by one is way too time consuming. In short, just do not buy this product if you want to retrieve the data stored in the device's memory: it its a pain and the measurements are not properly structured. Update: The issue of data loss when downloading is solved in driver version 1.22 (which I had a very hard time finding). But the pain of having to download all data day by day still remains.
