The customer service is Superior to any other company I’ve ever dealt with when it comes to a money-back-guarantee. Speed, responsiveness, and refund all within an hour of my first email. A++++ And, while the Novo Flow didn’t provide the relief I expected, I wouldn’t hesitate to purchase products from Cleriva.

The customer service was very good. The agent was I received a full refund for the NovaFlow without any problems as I thought I was buying the NovaFlow 2.0 and got the original NovaFlow. Well done!

I have ordered a lot of things online. Some companies have good customer service some do not, then there’s Cleriva. If I could give them 10 stars I would. Coney responded in less than hour and resolved my issue, no questions asked.

I was sick with sinus infections for years every 6 weeks. I went to an ENT. I had 3 surgeries that did not heal this. I was on prednisone and antibiotics for years. It just made me gain weight. I went to 3 ENTs. The last 4 years it got worse. I was sick every day with extreme pain in my head and sinus. I tried everything. I’m a functional medicine practitioner so I tried many natural remedies. Nothing worked until I bought your 2.0 system and use it three times per day. Within days I was well. I can walk my dog around the block. I remember becoming hysterical crying in the new ENT office when he looked at my cat scan and said there’s nothing he could do. Thank you so much for the research you did. It saved my life. I’m 72 and still may have a few years to live a normal life. I recommend this on Reddit for people who are suffering. Thank you.
