Ms. Coney Angel Arcilla was very kind and understanding of my issue. And also my technology shortcomings, She is an excellent support manager for your company. You are very fortunate to have her working for your company. Very fortunate. Please continue to promote her within your company, Thank you. Charlie Schnell 11/13/25

I am a 78 year old widow & take my health seriously as my responsibility to take care of it & seek the best products to help me. I saw Cleriva's ad for NovaFlow & was inspired to try this product to help me with my severe running nose & headaches along with my heavy phylum. Once it came I opened it & used it after readying the instructions. It was easy to use so I relaxed & watched the clock & it's timer worked flawlessly. The next day I used it three times because the instructions recommended using it 2-3 times in 10 min sessions. I look forward to daily use of my NovaFlow. I recommend this product that was quality made & packaged with great care. I believe I will be relieved of symptoms the longer I use it. I already see great promises of it.

This product didn’t work out for me, but the company provided the best customer service I’ve had in many years!! Highly responsive, with a no questions asked refund applied to my account faster than I expected. I would definitely do business with this company again! Excellent!!

I had an issue with my order, had the spare nasal parts missing, I emailed straight away with an image of proof and Coney Angel Arcilla from customer support replied almost straight away and told me they would send the spares out straight away. Great customer service.

I received my order after a bit of confusion with Royal Mail. Customer service has been great. I have been using this for around 3 days now, x 2 per day. I am seeing improvement and there is less pain around my sinuses. I would recommend this product.

Coney was very helpful in getting me a replacement when my device wouldn’t accept a charge. She got back to me the same day making sure I would get a replacement. I love this product and after such great customer service from Coney I will be shopping their other products

My customer service rep was excellent. They were quick to respond and handled my issue with understanding and solved my issue quickly. I’d give 10 stars if I could. Thank you Gail Tripp
