Not perfect, but pretty good...

Having just gotten cross-checked in the mouth losing 2 teeth and damaging another requiring $8K of dental work, I thought it time to move off the half shield. I tried this on a whim. Hate having to unclip and move it up off my face to wipe sweat and drink, is a pain but managing it. The shield gives good visibility and doesn't fog if you use a defogger and keep it clean. It's hotter than a pure cage or 1/2 shield. Most importantly, you must adjust your helmet to fit tightly on your noggin. Otherwise the weight of the shield pulls the helmet down in the front. Once I did that, it worked fine. If you face is not the same length as the mask, the molded chin cup doesn't quite line up perfectly and you can't adjust the chin cup. In my case the bottom of the cup which should be under my chin hits the bottom of my chin. Thinking of replacing it with flat foam piece.
