Product review (5 stars): Left with a bad taste
I paid premium for this item thinking that it is a genuine article and my peace of mind is worth the extra bucks. For whatever reason, water tastes horrible. I thought it would go away after a while, but well, a month later it still doesn't. I regret buying this item.

Update Nov 2016: even the best of us make mistakes. I had not installed the filter properly. I pushed it in and voil, it started to actually filter water. Water came out a bit dark and somewhat oily at first, but after a couple gallons or so it cleared and the taste is great.
