From the first application, I was thrilled. My mask has since never been launched. I spray a mask before each snorkeling because the soak overnight I forget anyway. And I'm also sometimes spontaneously in the lake, without that I already know that the day before.
Once Spray is enough for several snorkeling gears. I have tried it extensively in the Atlantic and also in inland waters (lakes and rivers).
I'm not going without this spray into the water.
