BANZAI Fogsaver Ultimate Fog Repellent Nano Coating Spray For Spectacles Goggles And Safety Glasses With Micro Fiber Cleaning Cloth - (17ml, Pack of 2)

Had ordered this product as I was looking for a solution for constant irritation on my glasses due to fogging because of wearing masks....and this product has solved the problem to a great extent....used it once and have seen no fogging in the past day and a half on my glasses. The instructions on the packing were a great help to application of the same.

Works exactly as it says. Apply as instructed and you're good to go. Really helpful in using spects with mask.

Comes in a compact case and mentions 200 sprays.I have used this on my spectacles a few times - as instructed. To reiterate -- first cleaning the spectacles (as normal)- after that applying the spray (takes more than one spary to get enough fluid to cover the glasses)- gently wiping with the provided microfibre to spread the fluid evenly- waiting 20 minutes- rewiping very gently to ensure any smudges etc wiped awayThis product is then supposed to prevent fogging up for the next 12 to 24 hours.**It does NOT do so** most often one side of the glass or one glass gets fogged up pretty soon while the other side may or may not fog up for a while - there is not pattern to the "anti-fog" . In fact the fogging up of the glasses is pretty much as before.I don't think this anti-fog spray is designed for condensation caused by temperature differences or mask induced upward condensation. In which case it is really of *no use*regarding the 200 sprays - even a smaller side spectacle glass takes 2 - 4 sprays per side - that is between 8 to 16 sprays for the whole spectacle - to get enough fluid to cover the glass surface. In which case the 200 sprays is at best 25 applications on normal spectacles. so do not get led by the 200 sprays figure*Would not recommend*

Waste of money

I wasn't successful in using it. It still fogs. let us know if you have been getting any success :)

A very effective product. Used it on spectacles while wearing nasal mask and the glasses didn't fog up at all. Spectacles didn't develop fog even while stepping out from air conditioned car to outside during rainy conditions too. Product performance lived up to my expectations and I highly recommend this product for spectacles and sunglass users.

Excellent innovative product. Worth when wearing masks have become a norm. Does a good job antifogging on my spectacles when mask is on. Worth it.

Not a great product. Instructions say that the sprayed liquid should be rubbed gently on the glasses and extra lines to be wiped off. Wiping off process removes the thin layer of coating and fogging occurs. Very badly designed as the application does not work as instructed by the manufacturer. Strongly advice not to buy this product.
