I was using my friends empire eventz a week ago and they felt NICE! Much better than invisins or profilers in my opion. The padding was perfectly placed and the vision was awesome. But as i started to move my way up the field and breathe more, I felt restricted. Since the ventilation is mainly in the front, my face got warmer much quicker than with Invisions, profilers, or any other "high-end" mask. They are pretty good, but i'm not buying them anytime soon.
It's definetly a good mask, but for that price profilers are probably better.
