Love the water Love the water. Set up is easy. We have very little counter space, so we had to set below the sink. This means a different set up, and the water does not immediately turn off. It takes about 15 seconds as it dribbles to a stop.

Excellent after the sale customer service I purchased Cosan water filtration system Jan 2017. I use it everyday and love it. In April 2018 I received a 15% off coupon reminding me to purchase and change my now year old filters. I missed the deadline! to use the coupon. Bummer. But, how proactive of Cosan to remind then entice me to purchase filters (supposed to be changed every 6 mos or so)! I wrote an email thanking them and hoping to know when another great coupon would come out. I received an email promptly offering me 10% off as I recently retired and let them know any savings would help. They worked with me while also being nice. I love the response time and actions!

water pours way too slowly -

Was not pleased with customer service or company standards. The main reason why I am giving a 1 star review is their customer service was pretty rude to me when I wanted to return my product. The rep I spoke with rejected the return and after a few emails, finally said the only way they would return it is if the box was never opened and they would have to take a $100 restocking fee. I also believe that the filter replacements are extremely expensive, not to mention the apparatus itself is about $500. Finally, my last complaint is that I was not able to use my warranty as the time for me to sign up elapsed since I was in the midst of trying to get an authorization to return my product. Overall, a bad customer experience to say the least. To be fair, the water filter does appear to be working well so it is a good product. It brings up the PH of my water 2 full points from 7 to 9, but my review is based more so on the company. I will not be recommending them to anyone or purchasing from this company moving forward.

Improved Quality of Life I have been using the alkaline water system for approximately one year. It has changed my life. I have sung the praises of this system every time I have had the opportunity. I have struggled many years with food allergies and sensitivities that affect my gut and skin. The improvement has been remarkable and drastic. The only water I ever drink at home is alkaline. I carry the bullet with alkaline water when I can. I highly recommend this product.
