Review on 🚰 Enhanced Filtration Capacity of the iSpring RO100 Drinking Filter System by India Stack

Advertised with 1 year warranty. After you open the box, it says in several places that you need to register with the company to get a one-year warranty. In terms of reverse osmosis quality, my city water is around 300ppt and output water is typically 27ppt. That's good, but not the advertised 99%. Installation was a nightmare. The instructions look like they were written abroad. There are parts in the kit that are not even in the instructions. I have no idea where to go. There's also a constant small amount of leakage unless it's installed a certain way, giving the lines a long, straight line to the ports. The sink mount was great and easy to use. I don't know how to change the filter.
