"I will need to come back in 3-6 months. We are currently in northern panhandle of Texas. The water is very hard and high ppm (921). I need time to tell if the 4 filters is better than 2 filters. We leave in 3 weeks to work in NM for 2 months."

"More like an ultimate waste of money. I tried it out before a trip… seemed to work. Then the next time I used it, the flow was so restricted I could not use it. Now water won’t even trickle out of it. Still waiting for a solution with customer service. Buyer beware."
