Very satisfied,

Very easy to operate and don't mind filling up large bottles in the sink, Just have to rig up a small hose to the small goose neck to the bottle or whatever. Have to wait till I get my first bill since I had this thing since 2 weeks ago today to see if it saved me any money. If anything it beats having to go the the store and refilling them there twice a week. My unfiltered water reads 127 on the TDS scale and 3 after it is filtered.

I regret not doing this sooner.

I have this thing about my tea and my ice being clear. I have tried several different countertop filters with no success. But this RO system has done it. No more murky tea or ice water, no more floaties, and great taste. Also, no more buying and lugging cases of water around. This thing will pay for itself in 2 months. Im so impressed with it and so disappointed I wasted money on those other filters(I spent enough on the other filters to buy this RO system and have money left). This was easy to install, except I had one little issue. I put teflon tape on the connecter to the faucet, even though it had an oring, I didnt see anywhere in the directions if it should have teflon or not, but i didnt want leaks. Anyway, i broke the first connector by overtightening it, luckily there was a spare. I didnt put teflon on the second one and had no issues, and no leaks there or anywhere else. The water quality is great. Flavor is great. Ive been using it for around 20 days now. I highly recommend this system.
