Product review (5 stars): These work Great. Very compact
These work Great.  Very compact, has all the right information.  The only downside is with the High's and Lows.  The device only records those every 36hrs or so says the manual.  This is probably so its always monitoring the Highs and Lows of a certain block of time.  I wish this was configurable, and also showed when the high was recorded.  Would be much more helpful.
