Title: Hesitant to say this is a perfect product
Review: While the detection and usability aspects of this product are phenomenal... I am a little hesitant to declare that it is a five star product because I've seen some finicky behavior where it will sometimes say "Self Cal" for a moment and then revert back to its normal "Autoscan." Once (and only once), it said "Service Unit" or something like that, but I reset the power and it went away...
Is the review positive or negative?
