Product review (5 stars): Good product
I was some what worried about these since the recent negative reviews. However after reading the manufactures responses to those negative reviews decided to buy again. I gave them a soak in a filter water bath for a couple hours to get rid of the potential of air bubbles and ran the water from the frig for a a couple gallons to get rid of any lose carbon and as advertise it has been working without any negative feedback since I installed a few days ago.
