Not perfect but works much better than one we got from big chain sports shop. Plus, it’s reef safe!

Works quite well.
Verified purchase
It's best to put a drop on each side. Rub it in well, then rinse briefly with a little water. As long as you don't get water in the mask and don't constantly remove it, it will stay fog-free. No burning eyes, even if you use too much – unlike with liquid soap. No bubbles left in the lake if you use it there. Hopefully not as harmful to waterways as liquid soap. About as effective as liquid soap. Works quite well. The bottle cap is a bit fragile and broke when I dropped it.

It really works without causing eye irritation, even during a long swim the mask does not fog up and does not harm the ocean.

It doesn't fog up when used. The effect is good. And there's hardly any smell.
