I have used this product for over a year now and enjoy it. The setup and 6-month replacement process is very simple, and the water is clean.

The first thing I noticed was the shipping packaging. You can tell a lot about a company, by how they treat their product during shipping. Every box fit perfectly in the shipping box, and everything was secured. Good first impression
Second was detail in set up. The instructions said to watch the YouTube video first. I was able to assemble the RO system via the video. It really was easy.
Once set up, no leaks, drips, or cussing. I rarely put something together without a £€~^##, along the way. Didn’t have any of that.
End result was delicious water, at the tap. Thanks iSpring for making our lives better.
