Product review (5 stars): Works great
Genuine product. Works great. Make sure you use a measured container to run the initial volume of water through it. It's a lot more then I thought I was going to be having guesstimated in the past. The result however is there's no risk of not getting clean tasting water once you start drinking it
And as for a two pack - no brainer. Annoying product to have to buy so cut those moments in half.
