LUCA V-Defense™ Nasal Spray with Lambda Carrageenan, Menthol, and Eucalyptol – Drug-Free Nasal Congestion Relief – Moisturizes Nasal Passages and Reduces Contaminant Adhesion – 0.67 fl oz (200 Sprays)

Very easy to use, not uncomfortable or anything. I don't like nasal sprays--I have pretty bad allergies and even though all my doctors told me to use nasal sprays, I just can't do it. I hate the ones for migraines too; they're just likely to make me vomit sooner. So, when I say that this is comfortable and easy to use... that means a lot for me lol.I can't really prove whether this prevented covid, but I used it religiously on a cruise and did not get sick. Of course I'm up to date on my boosters, masked in busy areas, used CPC mouthwash, etc. too.

You should definitely purchase this item for all seasons and it keeps you from getting sick.

I travel a lot and use this when I on airplanes or at Trade shows or large events with a lot of people. So far, I have not gotten sick while using this product. Unfortunately, I can’t tell you 100% that this product does what it says all I can tell you is that I haven’t gotten sick while using this product. I have a compromised immune system also.

Ease of use.

Excelente producto, me mantiene la nariz despejada

I don’t think this product really does anything it’s also unpleasant in terms of the chemical smell and taste that ends up in your nose and mouth. Maybe it works for some people but I did not like it and will not buy it again. Please be aware of this product is non-returnable.

This is a fantastic product! I have tried various nasal sprays and this one shines above the rest. First, it's important to consider that this is not a spray to be used after being exposed to airborne viruses. This is a preventative measure before exposure and if used for that purpose, while it is hard to prove effectiveness, I can say that I feel confident it works! I've tried other products that all have limitations,whether it be limited number of sprays or the product causing burning and nasal irritation. This product lasts a reasonable amount of time and causes no discomfort. They also have a very comprehensive set of tests they've shared that support it's effectiveness in protecting against airborne threats. In general, I strongly recommend this product to keep yourself protected in public spaces where wearing a mask is not possible or desirable. Very good product and very good price!

So far so good..no burning and no smell...Hopefully it works...I will keep a log and get back to you when in high crowds warding off germs..:)
