The device funktionniert well, both on XP and Win7. Software is simple and allows revision in Excel. Only criticism: Zoom option to a very limited extent. The installation of the battery is not comfortable but the exchanges are not every day. Unknown is the sensitivity, specially during rapid changes in humidity, since only a few holes to bring the air to the sensor without air drafts. Compared with other solutions such as USB flash drive does really cost and in all cases, what he should. I do not regret the purchase and would buy again the device.
