I've got one of these, and it works quite well for displaying 3-D content (haven't tested 2-D to 3-D conversion because that's nonsense, of course). I've been skeptical of ColorCode for years because the blue filter is so dark, but it really does work well. Just relax and let it work. The ColorCode propaganda says it works because you get most of the color info via the amber eye and the blue one just gets enough of an image to get depth. Seems to work because if you shut or cover the right eye, it does flatten out, but I'll admit I was really skeptical until I tried it for a significant period of time. And the included glasses are much better than the cardboard Superbowl/Sobe water glasses I have around, though I haven't really studied them for diopter correction or whatever.
It does make the picture darker- darker even than the other anaglyph color combinations- but they provide a brightness setting to help compensate. That does blow the high end out, so probably better to adjust your display if you can. In my case, the calibrated setting I usually use on my projector is below the 0 level, so I made another preset that was turned up a bit. (I do the same thing for shutters.)
Out of the box, it didn't work at all on a 3-D Blu-ray. Screen went white but audio passed. Firmware update fixed that. Firmware update is easy: put firmare file on thumb drive and plug it into the unit. It'll update and reboot. I had to stop the BD completely and restart it to get it going after the update, but it's worked ever since.
Got mine for $50 from woot at a recent sale.
