Product review (5 stars): Not perfect, but does what it is advertised to do. Overall I am very happy with it.
Not perfect, but does what it is advertised to do and seems to be reliable.  Overall I am very happy with it.

Here are a few areas where it could use improvement:
1. The software for this comes on a provided CD and is not available on their website.  Don't lose the disk!
2. When connected to USB, the internal power dissipation in the device causes the temperature reading to be a few degrees higher then it should be.  The best solution to this is to use the external temperature probe.
3. The exported data in in Microsoft Excel is in text format and needs to be converted to numbers in order to be graphed.
