The "liquidator" intrigued me as well so I called both the manufacturer and a dealer.

The manufacturer said it worked perfectly and you only had to clean it somewhere between 6 months and five years.

The dealer gave me a much better balanced scenario. In essence, there's no free lunch. You get to trade off adding bleach every day for cleaning the unit thoroughly around once a month....depends somewhat on the hardness of your water.

Second drawback....once you set up the unit to meter out the Cl evenly, you must constantly adjust it because the Cl is diluted continuously as the pool water is passed over it. That may not be a big deal, but for me, that's a deal breaker.

The website is hasapool.com and there is a dealer list to the right on their home page. I still think it's a nice idea but, when I add up the additional work it presents me, I'll just stay with Clorox.
