Product review (3 stars): Calling It Large Is Deceptive
About it's accuracy I am not sure since there's no good way to benchmark it. But my real complaint is the phrase "large digital display". The length is 3.4".  How "large" can the display really be? Totally my fault for not reading the info on size. I guess I was thrown off by "easy to read". Yes, if it is  a few inches from your face, it is clear.  But a few feet away, it is pretty small. I wish there was a large digitial display that was about a foot long.  I'm not thinking of carrying it around.
