Great RO system
We had another system and the filter housing was leaking, couldn't get it to seal back up. It was about 10 years old, so had given us a lot of good water. We decided to get this system to replace it with. This was so simple to install. The instructions were very clear and easy to follow. I will say i dad it easy because there was another system installed that i could look at, but if i had to do it from scratch, i believe that it would be simple to install. The water is tastes good from this system. Fits under our sink, even with a garbage disposal. It is tight, but still room to work and change the filters when needed. Would definitely recommend this system for anyone looking for a good RO system.

Freakin love this system and wish I'd bought an under sink sooner
If you've been hemming and hawing about getting a system, just do it. You don't realize how much water you use throughout the day, pets, washing veggies, boiling, iced coffees, etc. I had a little manual reverse osmosis but quickly realized how much water I used and what a pain it was to refill the thing the whole time. Upon recommendation from someone on Nextdoor, I got the system with the alkaline, found a local plumb who charged me $125 to install, and voila! Water tasted great, I'm instantly drinking my daily recommended water and then some bc it's accessible and tastes so good. Love that it comes out of the little faucet. And really the cost for the convenience of good water is wayyy worth it. Note: After the plumber installed it, I sat waiting and waiting for the tank to fill. Nothing was happening although the connections were right. I was like damn it, I'm going to have to return it or maybe there's not enough water pressure. I by happenstance of luck just in desperation to figure out what to do realized there is a pushdown small pedal-style water activator with a piece that clicks over the pushdown portion to lock it in the pressed down position. YOU WILL HEAR WATER IN THE PIPES. That's how you know the feed is active. It does not look like a traditional valve switch. So anybody who bought this and thought it didn't work, it might be that you have to push down and lock into place the pedal valve feed.

No more irony/sulfury well water!!
We have well water with high iron and sulfur smell. We received a quote for a RO system from one of those big name water companies for over $2,500. I decided to search elsewhere. I came across this system and the reviews were promising and its specs were comparable to the system I was quoted. We also liked that you could upgrade the system with more stages later on if needed and that all of the stages use filter sizes that are commonly available. Shipping was fast. The system was packaged incredibly well and came with excellent directions, leading to a quick and easy install. This RO system creates fantastic tasting water with zero smell. We saw no change in water pressure, although time will tell as the system’s filters get older. I can’t recommend this system enough! For the price point, it’d be hard to beat!

Tank leaked had to re-tighten it a couple of times
Just just make sure you make the tank not leak

Works great Easy to install
I was so nervous we'd not be able to get it installed ourselves. A lot of people complain about a periodic draining noise this with some research is a flush of the filter system when refilling the tank. It works great tastes great looks nice and saves our wallet and our backs not having to buy the watercooler jug refills. We also had a small leak at first this again was our error one connection came pre taped and the directions didn't note this or say to tape it so we removed the tape assuming an error had occurred we just detached the hose re wrapped the co section and pro lem was solved!

Much needed! Love it!
When we lived in our old place, we were close to a local business that would fill our water cooler bottles with really good Alkaline water. When we moved, there was nothing closeby so we had to think of something quick. Our water in the house tasted terrible and the filters for the fridge did not last more than a month or two before the water started to taste off again. It took me around 2 or so hours to install the RO system. I didn't use the faucet attachment they sent with it, I ordered an all-in-one faucet from here on Amazon so I would not need to drill holes in the granite. Now we enjoy fresh, clean-tasting alkaline water right from the tap. The only thing I would say is an issue is the overall size and amount of space it takes up under the sink. Since the sink is on the island there isn't a lot of room to work with but we figured it out. Other than that small issue, it has worked flawlessly.
