This mask is great. Doesn't fog. Very comfortable. Light weight. Easy to clean. Great field of vision. I would recommend this mask to anyone, beginner or advanced in playing experience.
Weaknesses:
Nothing. This mask is the best I have used so far. the only bad thing is that it doesn't have much neck protection.
Conclusion:
Great mask, great price. I have been using mine for months now and I haven't had any problems with it. Anyone who says otherwise, should just go wear their JT mask like the rest of the players out there. Get this mask, you will not regret it!!!
