Wanted to wait a little time before i gave review. When i first got the product the RO filter was cracked and flooded my kitchen. Luckily, it came with a spare that when installed fixed the unit. I called customer support they said they would send me a replacement extra which i have no received. I do admit the water taste pretty good and solved some issues i had with taste when it comes to my other filter. The reason the review is 3 star is because start up maintenance, and the not receiving the replacement filter after 30 days or else i'd give it a 4.
