Reviewer:SGM R.on3/21/2014

Mask Defog-Not bad - I bought this with my order and used it as well as another brand in Guam. This worked well but you have to be careful not to use too much or it just goops up. Pretty much less is better. The other brand was thinner but I didnt see much difference between them. Overall this works pretty well for the price. The size is pretty large so it will last a long time.

great stuffso worth it! - Ive had problems with my mask fogging in the past, but each time I applied the defogger before a dive, its worked perfectly. The defogger definitely works better than the stuff they use on some dive boats (watered-down baby shampoo), which only manage to hold off the fog briefly. For anyone who has problems with his mask fogging during a dive, I highly recommend the 500psi Mask Defog.
