Product review (5 stars): This is a good unit. It has a feature most don't
This is a good unit.  It has a feature most don't.  The readings are adjustable.  We have three and it's nice to know that each has been adjusted to a known accurate unit.  They are easy to read and can be wall mounted or stand alone with it's own fold out prop-stand.  I am getting some good range too.  All in all, this is a best buy for the price.
