To be fair, I've only had these things for a day and maybe they will respond to some tweaking in the settings etc.
Good things:
Had no problems with driver, software updates other than having to download and install newer version of directX.
Aces High 2 is now directly supported with the latest Vuzix software.
Bad things:
Image quality blows, hard to see enemy planes and can't read distance icons.
Tracking unstable, can't seem to keep it zeroed.
3D?, Maybe but so far it's hard to tell with this sorry image quality.
So far not impressed, and if I can't get it working better I'd say spend your money elsewhere but I will keep you posted.
