PROBLEM: 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.

SOLUTION: Good Review

PROBLEM: I had some trouble figuring out where to find the batteries that came with it, so if you don't have a screwdriver (comes in small package of 4), think twice first about using it and ordering it right when you're leaving for vacation. You will need it at your vacation home.

SOLUTION: Good Review

PROBLEM: I'm very disappointed with this product! I purchased a set that was listed on my Amazon Wish List in December, 2012, from BuyItNow.com. It arrived at the end of May. Two weeks later after installing it and waiting for rain showers, another unit began leaking water by one wall of each shower. This has continued through to now, July 2013. The other two units remain dry. Buyer beware, these products will only last about 9 months max. Don't waste your money purchasing anything like this.

SOLUTION:
Bad review
