Product review (3 stars): Good thing we bought two
We ordered two, so that we could get the free shipping. It was lucky that we did, because no matter what we tried we could not get the first filter to work. We soaked it for the appropriate time, twisted it in as directed, and no luck. After some time & frustration, calling the manufacturer, and eventually giving up on that first filter, I tried the second one we purchased. After soaking, the second filter twisted in and filtered right away. I'm thankful for Amazon's easy return policy- just a simple phone call, print a return shipping label and off in the mail. Uncertain if we will order this same brand in the future due to our bad luck with this purchase. The working filter performs as described...fresh filtered water.
