Product review (4 stars): Great hardware - mildly annoying interfaces
Works great so far! I haven't used it excessively, but there is not anything wrong with it. It seems reasonably accurate and the included computer datalogging software works well enough. I struggled between giving it 4 or 5 stars because of this.

A few quirks:
No power button... it stays on at all times! Supposedly the battery lasts 3 months, but I believe that is without recording samples. I will wait and see.
Starting a recording requires you to connect it to a computer and set it up. A mild inconvenience instead of being able to just press "Record"
User manual isn't great to get started easily, but I was able to figure out the buttons with a little clicking around.
