The product is good, but the package came very damaged, to the point my country's post office attached a note saying that the package arrived the country in that state. I'm lucky that the jug was not broken, and came only with a minor scratch. The included filter also was a little damaged, some of the (I assume) carbon grains were loose in the bag, and the filter had some minor damage, but I was able to put it together again. I've been using it for little more over a week now, and it certainly filters out most of the calcium, also the water tastes good, almost at the level of my other filters, which are original brita, the cylindrical ones.
