Made in the United States
It’s bassackwards. In from the right out of the left. Are they sure it has a 150 gallon RO membrane? My other two from a reputable company have one membrane for 75 gph and 2 membranes for 150 gph. Very easy install with provided instructions. Working perfectly even without a water pressure booster. I’m at 40 psi. Adding booster will give you at least 80 psi.

Still a bargain compared to the "Saltwater specific recommended ones"
Long term user.... I bought my unit in 2019, I did add a booster pump with gauge and another membrane simply to be more efficient. never has it given me a problem and i Highly recommend it.. crazy at the price changes of our time in 2019 when I bought it it was $169

Good system.
It is a great starter system - especially if you are doing aquariums. Much cheaper than some comparable systems with exact same amount of stages. Only recommendation I have is change the DI resin if you want 0TDS. RO is producing 3ppm and I was not getting 0 output until I swapped out the resin. Not a big deal, it’s a disposable item of a system anyways. I make roughly 200 gallons/month with this unit. My water pressure is horrible where I live and get about 50 gallons in 32 hours.

Great
Pretty easy to install. Reading 0 tds after filling our 200 gallon, our area tap reads close to 800 so we needed a good system. Works much quicker than our old RO buddy system. One non essential item was left out of the package, however, they had great customer service and got the part to us quickly. Would definitely buy again.

Doesn't get any better than this !
By far the very Finest Quality RO/DI SET I have used since I began this reef hobby ! Consistent long lived elements and materials I had been hoping for over the last 33 yrs. Ive not had one problem with nor have I had any issues with the quality of the filter water. It does everything I need a RO/DI system for with no guesswork ! I would buy this again x 10 !

Poor customer service
So far had this system a few days have yet to been able to get it going since none of the tubing is connected right. The system itself is pretty good quality. With that said customer service is a joke two non working phone numbers and non working email and vague instructions on any installation is absolutely annoying

the company is excellent in following up complaint with clear instruction to resolve ...
I just give 4 stars because the seal is not prefect after carefully installation, few water dripping from 2 canister and at "L" join where main water supply goes in. However, the company is excellent in following up complaint with clear instruction to resolve the problem. In overall, the water is super clear and well purified. Would recommend this product to others
