Product review (3 stars): Works fine but Extech needs to update their software
The temperature logger works as advertised and the data seems accurate.  The price compares well with other USB temperature logging solution.  However the supplied driver only runs on windows XP but then I didn't try that hard to make it run on windows 7.  The software's user interface needs updating. It looks and feels like software from early 90s. I found the CSV export feature disappointing as the data needs editing and formatting before I could do any effective analysis.

I would prefer an interface in which the logger just behaves like a flash memory card with a single CSV files containing the temperature log, simple and effective.  No software beyond a spreadsheet program required.  I ended up analyzing temperature data in a spreadsheet anyway.
