Product review (2 stars): Temperature sensor works well... it's within one ...
Temperature sensor works well...it's within one degree of my other sensors.  The humidity sensor reads over 10 points higher than my other instruments, which is far beyond the +/- 5 stated in specs which came with this unit.  I purchased this to monitor humidity in a guitar case, and it's just not going to do the job.  Be aware that this item is not returnable through Amazon.  It has to be returned through the seller.
