Coney listened to my problem
Coney listened to my problem, told me what they needed me to send to show the product not working and help resolve my issue. And, they are standing behind their customer service and sending me a new unit.

Using the NovaFlow has practically eliminated my allergies. It definitely worth the money and so easy to use. My little device stopped charging though. I contacted customer support and was immediately helped by Coney. Coney replaced my NovaFlow, no questions asked. Highly recommend!!

Had amazing and speedy customer service with Coney. Had delivery issues which was totally the fault of Royal Mail. Modern day transactions are so cold and soulless and mostly underwhelming so it was a breath of fresh air to deal with a company that clearly values its customers. Well done Cleriva and massive thanks to Coney. They have restored hope that not all are out to get you !

Years of congestion, sniffles were reduced by the Nova Flow nasal red light therapy. The results were most apparent when they all came back due to my device failing to charge. Coney with Cleriva was quick in sending me a replacement unit so I could once again enjoy the benefits of a Nova Flow.

I love my Novaflow!, it has worked wonders for my sinuses, so much so that I no longer require surgery! I highly recommend getting one, it’s a game changer. Recently I damaged my charging cable, and contacted customer services, Coney the advisor was so helpful, and I couldn’t be happier with the polite, respectful help that I received, thank you.

Do yourself a favor and buy the same kind of device on Amazon for $15.00. The Cleriva ships from China, so its most likely the exact same device as the ones on Amazon. What a scam.

Hi Barnaby, Thank you for taking the time to share your feedback. While there are many similar-looking products available online, NovaFlow is not the same as the replicas sold on Amazon. Our devices are manufactured to our specifications, undergo quality control checks, and are backed by our customer support team, lifetime warranty, and 120 day money-back guarantee. We fulfill orders through multiple warehouse locations around the world to serve customers in different regions as efficiently as possible. We'd love the opportunity to look into your experience further and better understand the shipment details you're referring to. If you could contact us at [email protected] with your order number and mention your Trustpilot review, our team would be happy to review the details of your order and answer any questions you may have. We apologize for any inconvenience this may have caused and we look forward to hearing from you.

As someone with seasonal allergies and sleep apnea, this seems to be working. The power buttons topped working, but they said they will replace it.

The original order didn't take as long as expected, and also, when the device stopped working, they replaced it within a week!
