Purchased angel water system thru the Costco , they promised to me "now you water will be cleared and not smell " but it's still yellow and smells like a rotten egg! They charged me around $6000 for that system!! I have a lot of friends who have systems from different companies and that system cost twice cheaper and they don't have that kind of problems! When I contacted angel water and explained them everything, they offered to me one more additional system for $5500 , so total cost willing to be around $11500!! How I said before, I have a lot of friends who install system with filters and softener for price around 6k for everything and everything works perfectly already for a many years! I already waisted a lot of time on a phone calls and waiting for technician from them and told them for a hundred times we have only two ways, first to remove that system and return my money or fix everything and it's should work as its was promised! But they still offered me additional system and a thousand explanation what we can try but water still smells and yellow! Stay away from that company, they a scammers! With that kind of partnership Costco slowly destroying reputation!
