I worked several years in a fine jewelry store that sold this product. We used the dazzle stick from time to time to add a quick shine to merchandise that was just tried on and on days our jeweler was not there to professionally clean items. I was always impressed with the instant shine the diamond stick provided. The brush tip is very helpful for getting under the stones and in the setting where gunk builds up reducing that brilliant shine. I recently got engaged and immediately purchased a diamond dazzle stick of my own. It's the perfect way to quickly give my ring some shine before leaving the house. You simply brush, rinse, dry and go. I don't feel this product replaces the need to professionally clean your jewelry every now and then, but it does help with the maintenance of that new shiny sparkle.
