Bests & Worsts Reviews from Amazon

Works well and was easy to install. Directions were clear, and the seller (James) contacted me immediately to let me know there was support in case I needed it. I chose to put the tank in the basement underneath the sink, suspended in my floor joists. This opens up a lot of room that would have been used under the sink. My water has a TDS~500 before the filter and I'm getting ~50 after this filter. It's nice to have the peace of mind of clean water. I also really liked the clear filter on the first stage. It will help me keep an eye on the sediment that may be collecting, although I doubt there will much because I have Pentek 20" big blue filter as a whole house filter, using a dual gradient density 25micron to 1 micron filter that already filters out most of the sediment. We really like the taste of the water out of this unit. It tastes like good bottled water. I haven't tried it without the alkalizing filter, so I don't really know how it would taste without that. I might try it without that filter in 6 months to see if I can taste a difference. For the line that I ran to the fridge, I used a 3/8" line that I bought from home depot. I bought the 25' length of tubing and 2 of the John Guest 3/8 to 1/4 adapters. It worked wonderfully and I have plenty of pressure at the fridge, too. I was worried about ice cube size, but everything has been working well. We have a family of 3 and this unit makes plenty of water for drinking and cooking. We've had it installed for about a month and have never ran out of water. Thanksgiving will be a good test for this, but I might just fill up a couple of pitchers the day before just in case. 4 month update: We made it through Thanksgiving and Christmas holidays with no problems. We never ran out of filtered water while entertaining friends/family. Making gallons of iced tea, Kool Aid, coffee, drinking water, and ice cubes, this system kept up. I was a bit leery of the size of the tank, but it appears to be sized just fine for most households. I have noticed that my TDS is now down to ~36, which is lower than the original 50-52 right after installation. I will continue to monitor this over time to see how long the Reverse Osmosis Membrane stays effective. In 2 more months I will be changing the filters, and will update the review with any issues. Josh from iSpring recently contacted me and was helpful at reminding me that filters need to be changed every 6 months.
