Well I think this is a good product. I don't carry baking soda and purifying tablets with me, because I use a water filter pump. Actually, I use my Camelbak at work, because I'm a cashier and I can't get away from my checkstand to get a drink of water. I hide the FlashFlo under my apron and clip the tube to my shirt under my apron. Since I use mine so often (every day), I love these tablets to be able to clean the bladder as frequently as I need. Thanks!
