My girlfriend and I drink lots of water and you can definitely taste the difference between the water that comes through this filtration system versus bottled/tap water. The build was quite a simple build - might be slightly heavy for someone who's frail. It's pretty big, looks cool and I even tested the alkalinity (using the tester you buy from the Pet Fish store) and the results were super alkaline! That reading must've been like 9 point something (super blue). I'm sure this product does what it says. No more need for water bottles. I just run the water through the filter and into my SIGG each morning which I bring to work. No more need for Spring water bottles or Dasani/Aquafina (if you research you'll see they don't remove Flouride - it takes too long). So in the end, I'm spending the same amount. =) Hope this review helps. This product is excellent in performance and value.
