I've overlayed the Sportmask cheater cage in blue over the Otny cheater cage in silver.
Looks like the bars just to the outer side of your eyes are further to the side for the Otny. Obviously the center bars are wider apart on the Otny. However, I put up a couple of chopsticks where I suspect the Otny center bars will be and I didn't find it to be in the vision at all.
The lowest horizontal bar for the Otny looks lower as well, providing a less concentrated lower area.
If I don't like it, I'll just buy Sportmask cage and replace. The Otny cage comes with stainless steel clips and screws, and neoprene washers....so it seems to be great quality.
