I've dove with a Visualator for about 2 years now. You've got to have a bigger face to use it. My buddy doesn't and it would leak on him every time so he gave it to me. I can make it leak if I violently shake my head but under normal use it's pretty dry.
Downward vision is superb. I recently had to use my Aqualung backup mask on a dive and realized how much more restrictive a conventional mask really is. I like the click detents for the vertical strap adjustment also.
If there is a downside, it's that it fogs fairly often, even after using any number of anti-fog gels, saliva, etc. I usually just keep an 1/8" of water in the bottom and swish it around occasionally.
