Bests & Worsts Reviews from Amazon

I'll make it brief, I bought a water tester kit and tested on water quality before and after installation of this unit. It has the same water quality nothing has changed. Water quality determined by the numbers read from water from 0-300. 0 for being the best water quality. Tested on bottled water, it's a number of 3, tested on my water dispenser from Primo water. It's a number of 50. Tested on Brita filter number is 150, without Brita filter it's 150 everywhere around my house and yes, I installed it correctly and followed all instructions. Also, it's flashing green light while water is being dispensed from faucet and I even let it run 10 minutes before I tested the water qaulity. Save you guys some money and don't even bother buying this.
