If you're looking for a water softener to reduce mineral build up in your water, this is the product you want. I have used RO systems before, and there isn't a whole lot difference between them.

Ex Output:
Good Review

This was a bad buy. It did not work properly and I am very disappointed with it. Not good customer service. After hours of troubleshooting we realized the unit needs to be returned for replacement. Hopefully it will end up working properly.

Ex Output:
Bad review

I'm a real fan of Michael Crichton books. That being said- I am not crazy about this movie. The characters were well developed with the exception of some other parts that have nothing to do with how they came together. It was like he decided on this scene without any really good story or character development. And then we see someone in another part and suddenly it's 10 years later.

Ex Output:

Good Review
