Summary: These glasses work fantastic. I got these glasses to replace the Xpand brand which I had nothing but trouble. I sent them back and took a chance on these. I am glad I did. I have a new Mitsubishi 3d tv 73838 and I am using a Sony Blu Ray 3d player. It is a DLP Tv with DLP link built in for 3d glasses so I needed no transmitter as long as I got DLP link glasses. These are very easy to use very comfortable and work flawless at all of my ranges.
Pros: Comfortable, Compact Design, Easy To Use, Good range, Improves Performance, Professional Quality
Summary: These glasses outperform Mitsubishi's and Samsung's glasses because they retain the high contrast ratio and deep blacks I'm used to seeing on my TV in 2D mode, and they don't require an emitter. The Mitsubishi and Samsung glasses require an emitter, and dark scenes become difficult to watch as the contrast ratio suffers greatly. The Optoma glasses correct this, and they're cheaper.
Pros: Easy To Use, Great 3D effect, Great picture quality, High contrast ratio, Highly Compatible, Improves Performance, Professional Quality
Summary: I posted the original review for these glasses. And since then I have tried 3 other manufacturers glasses and have gotten rid of all of them. Purchased another 2 pairs of these ZD101's as they are simply the best picture quality hands down. The other glasses made the picture quality washed out and if you read the forums you will see people mention dlp link glasses look washed out.
