There is nothing worth complimenting anything about this mask.
There is nothing worse than stopping in the middle of a game due to fogging and stretching the mask off your face just a little to get some ventilation. One of my friends have this mask. His fogged up so bad that he actually took his off during a game, told a teammate to cover him so he could spit on the inside lens and wipe it off with his jersey. Talk about taking risks on the field. The ear area is very uncomfortable. Feels like it will cut your ear. The visor is so damn cheap that it's warped.
I'll give my honest opinion about this mask answering the questions above:
Is the vision area good? Alright
Does it fog up a lot? "A lot" is an understatement, how about all the time....
Is it comfortable to wear? hell no
Does it stay on well? Nope, always have to adjust the hed-lok system to tighten it.
Is it worth how much it costs? No, and I wouldn't even consider wearing this mask if someone paid me to use it.
How does it compare to similar masks? It doesn't even compare, the quality of this mask is horrible.
Would you recommend it to someone? Yeah, if I really hated the person.
I've been regretting ever since the day I first used this mask. I should of read some reviews from this site before I even bought it. The photochromatic lens doesn't even help at all. Any mask should be the last thing you have to worry about when playing on the field. And for those people who gave it a 10, they are either in denial or work for the company.
