I haven't been able to use this item because it seems the plastic inserts are giving the water a bad taste. I contacted their USA customer service a week ago to find out what to do about the taste, and have not had a reply. At this point i will just send this item back. I am extremely disappointed in the company and the product.March 2009 update: it took me weeks to get a refund on this item from the distributor because the company was very difficult to deal with. Zero "customer service!"I finally found the perfect item, "the Penguin" and I love it!
