Arrived quickly, packed perfectly, easy to set up and the water is delicious!
I wrote an email with a few questions, and I got a speedy and excellent response from BARBARA G. The part I was asking for was sent to me immediately. The customer service is on top as well as the water quality after it has been filtered. I strongly recommend using the RKIN filter system for the best taste of water ever! Mariana
I found that using the Dual Function TDS Meter to be a thoroughly simple process. Everything about the device was clears as day.
I ordered the countertop reverse osmosis system but forgot to add the free tds meter to my order (oops!). Barbara G was super helpful and got one sent out to me right away. Within days, it was in my mailbox. Thanks for the excellent customer service!
