Review on Impressive ISpring CKC1C Countertop Filter Housing for Clean Water by Ryan Talcott

I have 2 of these filters. I have 2 different faucets. Tap with external thread, works perfectly. Female threaded faucet, adapter included does not work. I emailed iSpring about 2 weeks ago - no response yet. Update: iSprings asked me to call them directly to resolve the issue. I contacted Corey at iSpring; he understood the problem and sent me an adapter. The adapter works great. Corey should get a raise :) I've upped my rating to 5 stars as both filters work great. (And great customer service).
