Fantastic service

I placed an order and after a couple days I realized the wrong shipping address was put in by my GPay. I emailed the company after I received an email saying my order had been shipped. I sent an email and received a response less than 12 hours later saying they will intercept the order and ship to the correct address. I received a follow up email indicating that it is on the way to my house!! I was so relieved and so impressed at how fast this was done. This companies customer service is top notch!! Thank you for taking care of me and my order!! I wanted to add to my review. I have been using this device for 7 straight days, 3 times a day and I have no change in my sinuses. They are still blocked and mucus is everywhere. I'm going to give it at least another week because I really don't believe these people that are supposedly getting relief after the first use or first day. It just doesn't work that fast. Probably placebo effect. I really want to like this and give it a great review but so far it's a bust, a scam. I hope I'll regret saying that in another week or two.

Excellent customer service to resolve a problem

Excellent customer service to resolve a fault. My Novaflow stopped working after a couple of months. Coney from Cleriva’s customer service team was exemplary in responding quickly and arranging a replacement to be sent. It made such a difference being treated with real courtesy and consideration.

Great customer service! My shipment was delivered to the wrong address. Response was quick and once the address was confirmed, a replacement was shipped out quickly!

Brilliant customer service

Cleriva offer a money back guarantee which gave me confidence to purchase a Novoflow device. Unfortunately it didn’t work for me but Coney arranged a very quick refund for the whole amount and was kind and friendly in the email response. I’ve seen loads of reviews with people benefitting from the Novoflow and I would recommend people purchase with confidence knowing that the money back guarantee will be honoured by a company with integrity.

Instant Support

Received a faulty unit that would charge up.
I contacted customer support and was welcomed by a genuine, caring individual named Coney, he went all out to rectify the issue in an instant, by dispatching a replacement.
I cannot recommend the customer support which I've received highly enough....a real credit to the company.
Thanks Coney

Positive experience

Yes, I am happy to post a review. It look me quite a while to make the decision to go ahead and purchase, and it was a concern to be honest. I looked at all the alternatives on other sites, and finally made the decision to go ahead after checking out loads of reviews. My experience is that my concerns were unfounded which is reassuring in this day and age when often things are not what they appear to be. I received timely updates and it was delivered without any problems whatsoever. Not sure where it was despatch from, I thought maybe America, but there were no additional charges to pay. I have in the past had to pay duty from abroad so again this was another unfounded concern. I have also had further communication with their customer service on an unrelated matter, response was quick and pleasant, and I was really happy with the outcome. This was my experience and hope it may assist anyone else who finds themselves in the same predicament.

Great customer service.

I contacted Cleriva with the news that unfortunately my Novaflow had stopped working. I was still regularly using my Novaflow after 6 months to keep my breathing clear through my nose. I was delighted to hear back that Cleriva were going to replace my unit free of charge. Thanks Cleriva.

Sceptical at first, but…

I was very sceptical about this product and thought long and hard before purchasing, but decided to give it a go. I have always had sinus problems, asthma and now COPD and the winters are hard health wise.
I have been using this for a month now, during which I caught a cold, and the amazing thing was it was just a cold and I did NOT get a sinus infection. Still clear sinus wise, which also means my breathing is good. Long may it last! I know this is not a miracle product but it has seemed to help me a lot.

Wonderful customer service

Wonderful customer service, very responsive and timely to all questions. The product has helped me tremendously! I have had chronic inflammation in my sinuses and I noticed a reduction in inflammation after use.

I was sceptical…

I was sceptical that this would work for long term sinus issues including a post nasal drip but this has helped me tremendously. I use it every day, up to 3 times if feel slightly blocked up and have not been having the same sinus headaches or nasal congestion or discharge as before starting to use it a couple of months ago.
It did take a couple weeks to be delivered but it was worth the wait.

replacement

replacement
I ordered a Nova Flow in May. in Sept my puppy chewed it and destroyed the plastic posts that the cushions fit on. I asked if it were possible to replace the posts and the customer service rep offered to send me a new unit. I really appreciate this as I am exhausted from replacing things the puppy destroys and it was nice to get some actual support.

I finaly can breath

Although the device, for me, was pretty slow to start making a difference (i was cloged for years) when it finaly kiked in it did a great job, i can now breath all night from my nose and i sleep better. In order to have good results i had to jump from 10 minutes 3 times a day to 20 minutes 3 times a day to realy make a difference. The device is reliable until it quits (i have had 2 that just stop working after many months but the service is very good to replace the last unit ( the first one i just trash). I would appreciate more details on the utilisation like how long is it safe to use, do you stop when you fell better,etc. I highly recomand this product, maybe a more solid version for long time users
