Product review (5 stars): Item a 5, seller not a 5...here is why...
The item arrived quickly and was well packaged. The product itself made was simple to install and the positive water quality change was noticeable immediately.

The only reason I didn't give 5 stars to the company is because the description states that they are selling a 3-pack for $34.95 and that the singles are sold out. They still sent a single. I honestly didn't expect 3 and figured it was probably some sort of oversight, but the company should be more responsible with their listings and honor their mistakes.
