Bests & Worsts Reviews from Amazon

Original September purchase: product came in original manuf packaging, fits well and works fine. 12 March Update #2: went for more water and got the hammering sound. Upon opening the filter cartridge area, the paper towel I used to pad the cartridge is now soaked. Redid papertowel (little thicker) and when I went back to check on it a couple hours later, paper towel getting wet again. Just submitted a refund request. Will try to buy from a brick/mortar store to see if I have better luck or even try to find an alternate option. Will see what works! 12 March Update: bought again but had issues when I installed it. I’d get a hammering noise and then no water would flow. Searched high and low for the ‘how to fix’ and found it on a YouTube video. The latest cartridge I received was ever so slightly smaller than the last one, so it was making a complete seal when the filter compartment lid was closed. So upon advice from the YouTube video I put in a folded piece of paper towel (about 1/4 sheet folded up) btwn cartridge and door and Voila - it worked w/out issued! No hammering noise and water flows freely. Will update again if this changes anytime soon!
