Product review (3 stars): Product is fine but delivery system is WRONG!
I have used this product in my "whole house" humidifier which ONLY is able to raise the humidity to acceptable levels in our master bedroom, but I digress!  Disliking to trudge through store after brick-and-motar- storefront searching out an out of stock product, I resorted to my "search engine for all things to purchase, Amazon.com." I THINK the product does what it says,but I have no real way of assessing. No Legionaires Disease or other plague has befallen us, so we're good to go so far, crossed fingers!!  My complaint is with this recent bottle, accurately pictured  (above here.) It offers only a flat, attached cap. The directions for use (printed so only a well.....bacterium...could read without use of a magnifying glass!!) clearly advised against getting the product on person, ESPECIALLY EYES or clothing while pouring a CAP-FULL per certain gallons of water. WHA!??! HUH!?!?  Clearly impossible with this "new" to me delivery system!!  Being mindful of the dangers involved, according to the instructions, I carefully decanted the anti-bacterial agent into my former container with the REAL bottle cap measure.  Such an unnecessary risk for the consumer! Such slipshod production for the manufacturer! Doesn't anybody on the other end READ their own instructions for use!?!? DETAILS PEOPLE!! DETAILS!!! UNACCEPTABLE!!!
