Hi Tracy, I'm very sorry that you had this experience. I want to sincerely apologize for the frustration this has caused as we know it hasn’t been ideal, and that’s never the standard we aim for.
As we shared in the email, we did briefly sell out of stock but your order was prioritized as soon as we restocked. We also issued a 20% partial refund as a gesture of goodwill, since your satisfaction is very important to us.
I just checked the latest tracking, and your package has now arrived at your local carrier facility and is scheduled to be delivered by the end of the day tomorrow. We’ll continue to keep an eye on it until it’s in your hands and let you know if any other issue arises.
We truly regret that this order didn’t go as smoothly as it should have, and we appreciate your understanding as we worked to resolve it. Thank you for your genuine feedback. It helps us improve so that issues like this don't happen later down the line.
If you have any further questions please reach out to us at [email protected]!

If you're UK-based, DON'T go near this company!
I ordered this product on 10 August. I was told twice by email that it was "on the way", on 11th and 17th August. I have heard NOTHING since that date and will have to arrange to recoup my money. Appallingly bad service.
Unsurprisingly the item (obviously without its alleged and unwanted "free gift") turned up several hours after I posted the review. No warning of its arrival, the company's website "link" to its tracking didn't function once. If you want that sort of service then go ahead. Not for me, thanks.

Hi Stewart, we’re very sorry for the experience you had as this is not the standard we hold ourselves too.
However, we’re a bit puzzled about the emails you mentioned, as we don’t typically send shipping updates without including tracking details and whereabouts.
Regarding the free mystery gift, some are physical items and others are digital. If you didn't receive anything with your package, your mystery gift has been delivered via email.
While we couldn’t locate any emails from you in our system, we still want to make this right. We’ll be refunding your order in full, and you’re welcome to keep the product.
Please also feel free to contact us directly at [email protected] if there’s anything further we can do.
Thank you for your genuine feedback. We truly do take it to heart and use it to improve!

Over priced hype
Over priced hype. Gimmicky cheap product. Does not work as advertised, the only good thing is the nose plugs stretch your nostrils.
Not even worth asking for a refund.
You can find the identical product on Temu and Amazon for $9 (just missing the silkscreen logo).
Save your money and go see your family doctor.

Hi Troy,
I'm truly sorry to hear about your experience with our product and appreciate you bringing it to our attention.
I want to reassure you that the products you’ve seen on Temu or Amazon that appear similar are not our official NovaFlow device. While they may look alike, these are low-cost imitations produced by competitors. They are not calibrated to deliver 660nm red light, the wavelength supported by clinical research and used in our NovaFlow devices.
If you’re unsatisfied for any reason, please know that we proudly offer a 120-day money-back guarantee with free returns. Simply reach out to us at [email protected], and our team will take care of the refund process for you right away.
Again, I sincerely apologize for the confusion and any inconvenience this may have caused. I hope this helps clear things up and we’re always here if you need anything else!

3 weeks later and still no delivery of product.
Poor service. Could have got it sooner elsewhere. Not 100% transparent on their deliveries. Wish I hadn't of bothered. Will be returning and refunding when/if it ever arrives.

Hi James,
Thank you for bringing this matter to our attention. We sincerely apologize for the inconvenience you've experienced with your delivery. A three week delivery timeframe is unacceptable and likely indicates an error on the courier's end. Please email us at [email protected] with your order number, and we will address this promptly.
Thank you for your understanding, and once again we deeply apologize for any inconvenience. We look forward to resolving this quickly.

False claims and shameless hyperbole.
False claims and shameless hyperbole to sell a cheap product at unfair prices. £30 is expensive enough and that is with 50% off. I don't know how they could justify charging the full £60 on this questionable product.
Their website graphics claimed 87% experience relief in 48 hours. FAQs said 92.7% in 24 hours and the rest in 2-3 days. After I questioned this on a Facebook ad, they deleted my comment with no response. The website FAQs now state 87.3% in 24 hours, the rest in 3-5 days.
Therefore,100% experience 'full relief' within 3-5 days?!? I've used it for 10 and have not experience this. I've seen other customers who have had no relief too. How has their research resulted in a 100% success rate within 5 days?
The box says one charge lasts up to 45 sessions. My battery dies after 7.
I submitted a 1-star review on their website, however it was never displayed. I wonder how many 1-star review are ignored.
Update (24/06/2025): They offered me a full refund. However, they have blocked me on Facebook which shows they are continuing to censor reviews and are a disingenuous company.

Hi Pete,
Thank you so much for bringing your experience to our attention. We genuinely appreciate your feedback and would like to address your concerns directly.
The initial 92.7% effectiveness statistic within 24 hours was based on earlier survey results. As we continue to grow, we regularly update these statistics to reflect the most accurate and recent customer experiences. The current figure of 87.3% effectiveness within 48 hours is our latest updated data.
Regarding your device's battery life, our devices typically provide up to 45 sessions per charge, although this can vary slightly from device to device. However, if you're experiencing significantly fewer sessions, such as only 7, we certainly want to address this issue promptly. Please reach out to us at [email protected], and we'll be more than happy to assist you further.
With regards to reviews, these are managed independently through a third-party service, and we do not have control over their processes. Additionally, please be assured that we do not intentionally delete any Facebook comments. Occasionally, if we remove posts due to low engagement, associated comments may unintentionally be lost and removed with the post. We deeply value all customer feedback and would never deliberately remove honest reviews.
We sincerely apologize for any inconvenience you've experienced and hope this clarifies the situation. If you have any other questions or need further assistance, please feel free to reach out, we're here to help!

What they don’t tell you is the whole list of contradictions so you can’t use the devise such as if you get dizzy spells, nose bleeds, have a deviated septum etc, so it’s useless for me and then tying to get a refund is a waste of time as the email is rejected by their server
Response from ClerivaMay 8, 2025
Hi kamalsteve, we sincerely apologize for your negative experience and any miscommunication from our end. Our intention is never to withhold important information, and we appreciate your feedback regarding the device's usage limitations, we will certainly take steps to ensure clearer communication in the future.
Regarding your refund, please reach out to us directly at [email protected], and we will promptly assist you. We offer full refunds for customers who are unsatisfied with their purchase, and we are committed to resolving this matter swiftly for you.
