Replaced or a traditional undersink RO with this system and it seems to be the right choice. The ordering process was simple and receipt of the unit was very fast. I appreciate the fact that it doesn't waste nearly as much water at the traditional system not only because I live in the desert and that's anathema to my being, but also because I hated hearing that incessant trickle for 15 minutes while the traditional system balanced itself out.

Tankless Reverse Osmosis Systemm

I had a lot of trouble hooking up the unit. The connections to the water supply lines were not standard. I needed 3/8ths connections and I believe they sent me 7/16ths. Had to go to several hardware stores to find a work around.

Easy to install and works great so far

I like the system so far. It looks nice and doesn't take up a lot of space like my previous tank RO system. The water flow is good and the water is clean. I bought it because it's the most efficient at not wasting water at this price point and the replacement filter costs are reasonable (right now, I did buy extra in case prices increase).

It didn't come with a 3/8th inch adapter, it was larger than what I needed, but NuAqua was kind enough to credit back the cost to purchase my own adapter. I still need to install an undersink electrical outlet but the power cable is long enough to plug on my counter sockets so keep that in mind. I don't think the instructions mentioned to use teflon tape but it did help prevent leaks for me.
