I just received the item.
It is a very basic, no thrills item... and that's a good thing because it means its not flashy and fragile.
However, I tested it with my LG 100Hz FHD 1080p LED webOS TV... and the results are very mixed.
On low graphic fidelity images, like a Wii, X360, PS3, Wii U or Xbox One it just doesn't cut it, due to low-resolution titles.
If the games are rendered in 720p (or less), and that resolution is then halved, it just looks very choppy.
On top of that, there is some image bleeding from one player to the next, so light coloured objects stick out from one player to the other and vice versa. I think the let down is from the TV unit, and/or its reflective glass-plastic front.
And I suspect ALL glasses will behave the SAME way. Limiting factor is the game + console + tv.
Perhaps the NX, PS4, or PS4K could be a better fit, by rendering the image at 1080p to eliminate the choppiness.
A SteamBox or Gaming PC would be ideal if ran on 4K resolution.
And perhaps also using a newer TV set would alleviate most of the problems such as;
Matte display reduce glare, 200Hz panel might help hide ghosting, HDR-OLED for better colour "pop", and 4K resolution to eliminate choppiness.
But that's a quite expensive endeavour costing at least $3,000 (for TV) + $1,000 (for PC) + $100 (Game + Glasses) $4,000+
And I don't see it worthwhile unless it is for CoD/Halo/Splatoon/Basara/Mercenary Kings/Minecraft/Mario Kart/Rocket League.
For you and some mates.
There is always the choice of having a small 20-30" tv/monitor hooked up to another console and connected in a LAN network. Even that is rare these days. At least it won't cost as much ($600 TV + $300 TV + $400 console + $400 console + $100 game + $100 game = $2,000). So it would cost half as much, but would use double the electricity.
It's more likely both games and both consoles need to be connected to the Steam/Xbox Live/PSN network, which adds $100/pa in subscription costs. That's the anti-social (and expensive) future, even if most of us don't like it.
I hope this was insightful.
