Let me start off by saying, Best bang for your buck mask there is, period.
For what you're paying for you're basicly getting everything a mask needs to be.
You're also getting;
Stylish looking goggles in many nice colors.
Nice rubber parts to catch some bouncers
Quick lense change system
Best of the flock no-fog system in the price range
For $30 retail, thats amazing. I mean, thats where most masks I've seen start retailing at, and you know how those low level rental masks are!
Only weakness I had is with one of them, (I have bought 3, one for me and two for my brother/sister) is the visor broke. I don't rmember how exactly but it came off and the piece that holds it in had snapped. (thin rubber). But I never use a visor so it's fine. And like I said only happened on one of the three masks.
This is the perfect starter mask. Has everything you need + more. I'm the kind of guy who buys cheaper stuff for his first things, so this is what I got and I still use it to this day.
