E-Z Pool Concentrated Pool Blend

I recently came across a product while on the web called E-Z Pool Concentrated Pool Blend put out by a company called APi.  They describe it as a Proactive watercare program rather than treating on a Reactive basis after the problem has already occurred.  It is quite pricey, but considering the fact that you only put it in your pool one time per week and it includes all of the following I didn’t think it was too bad.  The following was taken from their site: EZPoolPRO contains a stable oxidizer, algae shield, clarifier, scale inhibitor, water conditioner and balancers (pH, Total Alkalinity, and Calcium Hardness) to keep swimming pool water clean, clear and trouble free. EZPoolPRO does not require additional cyanuric acid and helps to maintain low CYA readings.  I discovered that our local pool store carries this product and the owner told me that people seem to like it.  She also said that you only have to put one chlorine tablet in your feeder weekly.  Has anyone on the forum used this product?  I would like to know what you thought.  Thanks!
