I have PDI and invisiglass that came on machines when I bought them. PDI is clearly better, but I wouldn't buy a sheet its too much money. Invisiglass is second and I wouldn't buy that either. Just get normal tempered and save the money for another game or maintenance costs. People buying expensive glass might as well just light the money on fire.

Standard tempered is what games normally come with. It works fine and its cheap. The anti glare stuff does work but its so stupidly expensive its not worth it. You can go to a glass shop and get a regular sheet for $30 by me. anti glare is not worth 10X the cost. I'll keep it if it comes on a game. I'd never light that much money on fire for so little benefit. If you have even reasonable lighting the glare isn't an issue anyway. DMD games get a glare guard to stop the low angle reflection from the DMD. Don't light you backglass like your using it to signal aliens and you eliminate a lot of glare. Like I said it does work, it looks good when clean. Its not $300 worth of stuff you are paying to not look at.

I wouldn't take the glass or topper, neither does a thing for helping the game play. I'd hold the several hundred toward maintenance or another game. 10 games with overpriced, unneeded, (but nice) glass, or the better part of 3K to get another game? I'll take the game every time. you can run track lighting cheaper than a piece of glass. Then you can put your overheads behind the player so there is no overhead glare. the only glare then is the backbox. Glare from a window, close the blinds/drapes.

its your opinion, but its a bad one.
