My husband is an instructor and I'm a divemaster. We used this on our last day of diving, and it's fantastic. We put it on before our first dive, and it lasted all day. Great stuff!

Frog Spit, the best ever!

I have been using Frog Spit (the product!) for quite some time now. Since the product needs to be applied beforehand and dry before use, this has forced me to take great care of my equipment by rinsing it properly after use, and prepare it for the next dive every time. It also works on plastic lenses which suits me well given I use goggles for the pool (which I don't apply every time), and a Sphera mask for freediving. One defog takes care of all my needs. I suggest using the same after dive practice to avoid greasy fingers while applying. The product is like a soap also and helps in keeping the mask or goggles clean. It's perfect when used properly!
