Product review (5 stars): The first one we received was horrible, may have been a defective one
The first one we received was horrible, may have been a defective one.  Amazon allowed me to return it and replaced with a new one. The new one was different, it had the "BluePure" sticker on the filter and the tab to switch from the faucet to the filter was also different and so much better. I believe they sent us a generic one in the beginning which I would have rated it 0-Stars but this new one actually works and I would give it 5-Stars.  I hope it continues to function properly.
