Product review (1 stars): Warning!  Deceptive!
This is a flat out deception.  The 3 bottles I received are not the original blue label 3BT bottle that is the genuine stuff....I have a bottle of that for comparison in stock which I bought about a year ago.  Instead it has green and white labels on the bottles.  Why does that matter?  Because it is a watered down version of the blue label bottle.  I will post a photo of the two bottles with different looking labels if allowed.  This vendor, Great Household, sent me 3 bottles that have less than half of the important ingredients compared to the genuine blue label bottle from last year.  Yet, they choose to post the blue label as the stock photo....such crummy deception.  So, according to the label, I need to add 2 capfuls per gallon to treat my humidifier.  The blue label bottle says to only add one capful per gallon....so, you think you are getting a bargain here buying 3 bottles at a time when in reality these 3 bottles will treat the same amount of water as only 1.5 bottles of the blue label genuine 3BT stuff.  I thought I was getting a decent deal when in reality I probably paid twice as much as I was expecting in good faith because I need to use twice as much per treatment.  I really despise the con and deception of merchandise like this.  Hopefully Amazon will see this review and investigate Great Household.
