#1 - they shipped the wrong item to me, which I had to return and wait on the correct item to be delivered
#2 - when I got the classic aquatru it appeared the membrane was defective giving me a TDS reading of over 160ppm. I been doing water filteration for a long time and had RKIN RO system and now WaterDrop RO systems and they always been (after re-minerailization) around 25 to 28ppm. 160ppm was not correct.
#3 - Dealing with Customer Service at AquaTru was a nightmare and took tons of my time out of my life. They wanted me to pay to ship the defective item back - which took two calls to get that resolved. I sent the item back then had to make more calls to tell them I did along with the tracking number so I could get my refund (nothing like returning something on amazon!).
#4 - finally got reimbursed and will never buy anything from aquatrue again in my life. I bought waterdrop RO countertop system from amazon at $240 which has all the same certifications and after re-mineralization my same TDS reader displays 29ppm on the 4th gallon of water i put through it. on the aquatru classic i ran 7 gallons of water through it and still ready 160ppm. The customer service guy at Aquatru tried to make me believe this was normal - but youtube videos say otherwise (where they demo'd the TDS). If i was not experienced with water, I would be drinking contaminated water if i believed the bad customer service representative.

I will never do buisness with AquaTru again, because I don't believe they are True but try to tell you something is not defective and normal when it is NOT.
