Just purchased this cage last night and put it on my Warrior Krown 360 helmet.
I was planning to buy the Reebok 11K cage, but after I picked up this Re-AKT cage, I changed my mind IMMEDIATEY. I put back the Reebok 11K and paid for this Re-AKT cage.
This cage is light as it should be, Titanium material. It weight is about holding 10~15 pieces of plain paper in your hand. VERY LIGHT.
The only thing I need to put as "WARRNING" is the width of this cage. For people who have wider circumference of head like me. I am wearing KROWN 360 size XL helmet and I HAVE TO loose it all the way to the widest space. When I put on the helmet on my head, this cage actually has hard time to fully close to the place of the stopper. The chin cup is about 2 inches far from my chin......
Anyway, rather than having a cage that fits my helmet but too heavy, I prefer to keep this super light cage.
About the vision field through the cage, I will say there is no difference from the Reebok 11K. Both are designed to increase vision field, by using oval metal bar (Re-AKT) or flat metal bar (11K).
I will try its field performance on this coming Sunday, the first game of Summer season.
One additional note for the readers is that I recommend you DO prepare one cage in hand. You will need a cage when playing during Spring and Summer time, to alow the sweat that is running on your face and forhead be air dried. If you keep on using a shield, it just blocks the air flow path. I just experience that through the whole Spring season game, so I finally made a decision to change my Oakley face shield combo to this cage.
