They are the worst, I purchased a filtration system from these guys in April 2014 in worked great for one year but I've had a terrible time since I replaced the filters which I purchased from them I have not been able to get the system to work right since February of 2016 I have called them and sent emails trying to get them to help me with my system but they either don't care to help or are not smart enough to. I have purchased everything they say to fix my system to work for my family but none of their fixes have worked. So although they might have a good system save your money because they will not take care of you as a customer if you need it they just sell you the product and are done with you!!! Save your money and go elsewhere.
