Great stuff, works on car mirrors and windows too.

I recommend it works.

Preparation

I recommend

Spray

Excellent tool

Very satisfied

Super anti-fog product. I recomend

After application, my swimming goggles finally did not fog up

No fog

When I use it, my glasses and the mirror in the bathroom no longer fog up

A great helper when fogging diving goggles, but also in the car windshield during the winter

The glasses fog up, but less than without this spray.

it works

the spray works, but it pays to apply more layers

NO FOG feldten 150ml spray against fogging of glasses and visors

The product is absolutely ineffective against fogging when used on prescription glasses, even after several repetitions.
