Review on Aquasana AQ 5300R 3 Stage Replacement Cartridges for Enhanced SEO by Chris Drury

And if the instructions were just a better explanation of how to install everything, this would be the perfect product. For example there was no explanation as to why they put the battery in the box so it took me 10 minutes to figure out where it went. A simple image or two to explain things would go a long way here. There is enough space in the box for a large pack of instructions. I'm just saying. Or do what other online sellers do, which include a simple card with a quick link to an installation video.
