I have one and so far it has been great. On my last game I started experiencing fogging but don't know what was the reason, as it could have been multiple ones.
One, I was a bit more active resulting in my body generating more heat and swear.
Second, the winter time being colder that could influence the fogging.
And last the lens may be getting old, I had it for like half a year (usually you replace the lens once a year) and needs replacing, as it was fogging between lenses. It has two layers the exterior hard shell and the interior one which I believe is the one that has the anti-fog tech, both holding together with some adhesive dense foam.
I don't think I will change it soon as so far it has been great. Do take in consideration the mask is quite small (at least in my case) and doesn't cover the lower face so well (the chick is a bit exposed), if you open you mouth as wide as you can it will reveal you bottom teeth just under the mask (hard likely to get any hits unless you go full Bravehearth and shout Freeeedom). For me this works quite well as I have a small bladder and can easily hydrate during games.
You will have good field of view with it as the lens extends to the sides, so you will have good peripheral vision.
More to add to it is that the top part is quite wide so if you are wearing a helmet, it will require some modifications to it (plenty of tutorials on YouTube). I use a snap-back hat and I wear it backwards and always get shot in the bloody hole.
