Here in Las Vegas the water is very hard. Mineral deposits galore!!! I tried the competitor's product (Dishwasher Magic), and it cleaned the dishwasher well. To get the mineral buildup off the coffee pot and other glassware, I would have to purchase another one just for that purpose only, though they don't recommend you use it with dishes in the dishwasher. It gets very expensive for the product is about $4.00. To do the two-step process with the competitor, it has cost me a fortune just to keep the glassware clean. One day, I spotted your product on the shelf at Wal-Mart. Kudos to your design team who used large lettering and a bright colored package. If not for that, I wouldn't have seen the product on the shelf. Picked LEMI SHINE up off the shelf and read the product label. Could Lemi Shine really work as stated? It had a money-back guarantee (which I thought was a great marketing strategy). Decided to give it a try! Rushed home with Lemi Shine and loaded my dishwasher with all the cloudy dishes. The next morning when I unloaded the dishwasher I was so amazed!!! Every single item in the dishwasher had no mineral buildup!! I was so pleased; I called a couple of my friends to tell them of my new discovery with Lemi Shine! Goodbye, Dishwasher magic and hello, LEMI SHINE!!! Thanks, Lemi Shine for your wonderful product. If you need a spokesperson to canvas the Las Vegas area and hand out free samples and coupons throughout the neighborhood, let me know. I have that much confidence in your product!!! Btw: My two friends just called me today and were shocked by how well your product worked! Keep up the good work LEMI SHINE!!!!!
