5⭐CS

I've had some difficulty with my device charging so contacted the support team, I spoke with Coney who I kept in regular contact with as I wanted to monitor my device for a few days but still found it wasn't holding charge, I want to keep using the novaflow as I have seen the benefits after only a few uses (my partner has noticed I've not been snoring which he's happy about 😂) Coney was a great help in supporting me with my issue and has arranged for a new device to be sent to me so I can continue to feel the benefits, I was very impressed by how quickly my emails were responded to which gave me confidence in the company.

Customer Service and refund

While the equipment was of good quality, after trying for several weeks I found it did not work for my situation. I was extremely impressed with customer service when I requested a refund. The response was quick, efficient and pleasant. Should have my refund in a couple of days. Thank you Cleriva.

Great customer service!!!

I haven't used the product but I'm impressed by the customer service department. I ordered Nova Flow because I've had chronic nasal congestion for past 40 years and I'm addicted to using fast acting nasal spray. I know it's bad for me but I really like being able to breathe through my nose. I use it 6-9 times a day. I'll try anything to get off this rebound Rollercoaster to constant congestion. I've scheduled a septoplasty with turbinate reduction and my ENT wants me off everything before surgery. Nova Flow customer service was very kind and sincere in accommodating my recent order request. I don't know if the product works or not but I appreciate the professionalism they've shown me thus far.

Outstanding service

The delivery was left in the wrong place and I couldn't find the package. Cleriva immediately refunded me then a neighbour found the package, but Cleriva still refunded me. That's amazing customer relations!

After 11 years of chronic sinus…

After 11 years of chronic sinus infections due to an immune deficiency, countless doctors, tests, and medicines, my ENT just told me that my sinuses look the “calmest” he’s seen them. The change? This product. I have been using it daily for about 6 weeks. My husband rarely notices my snoring. I can breathe so much clearer. My sinuses are still far from perfect but I am a believer and so thankful I tried it!

Incredible customer service

I bought 2 items in error and I was dreading and putting off contacting Cleriva to ask for a refund because I thought it would be such a hassle but instead the response I got was amazing! They replied straight away to my email. They offered me an immediate refund with no further questions and even without the need to return the original items. Just brilliant! They have restored my faith in on-line shopping!!

The customer service is top notch

The customer service is top notch. No questions asked return policy. Refund was immediately issued after I sent an email requesting it. It's not often that you get customer service like this and it's obvious this company takes it's customers satisfaction very serious.

I am so glad that I discovered this…

I am so glad that I discovered this brand. I have suffered with chronic rhinitis for years. So I decided to take the plunge and purchase the basic Nova Flow device. Within about three or four days the continuous nasal drip began to decrease. Alongside that the sinus pains in the back of my head began to diminish. At last I have something that stops me feeling if I am walking around with a lead weight inside my brain. I was so impressed that I purchased another kit, the full package this time with the steriliser, for my husband who is a heavy snorer . Already I can enjoy the simple pleasure of lying next to him in bed and listening to his gentle breathing without feeling that I am stuck in the middle of a pig Farm from all those strange grunting noises that have now, thankfully, vanished.
Highly recommended!
