I assume that many have replaced their W1070's for newer models by now, so maybe it could be regarded as a general "DLP 144hz" topic. For anyone still finding this topic interesting, here's an update from a "Gonbes G05" owner.
The G05's are these: http://www.gonbes.com/index.php/en/info/97.html
Anyone who's been looking high and low for 3D-glasses on eBay, Amazon and the like will notice they look exactly like other glasses branded as "Ultra-Clear", Sainsonic and several others. There's no way for me of actually knowing if they are in fact identical or not, especially since even within the "G05 DLP" family, the glasses are different! I know this because we have three pairs (bought four but one was broken), and one of them are unmistakenly different than the other two. The look EXACTLY the same, but they are not.
I see no real difference in the actual picture quality, but with all of the glasses we've been having sync issues when the picture goes bright. On our former PJ, a Benq W1070+, we only had problems in extremely
bright scenes, no big deal really, but on our current PJ, a W2000 (aka HT3050) we see the problem in all
fairly bright scenes. But here's the thing: one of the glasses hold sync much better than the others, and when they do lose sync, they flash slower than the others - once every third second on the "good pair" opposite every second on the "bad pairs". Sorta good news, problem is we only have one good pair and we need at least three glasses!
I can't technically explain why we have more sync issues with the new projector, as the glasses should be compatible. All I know is, in order to minimize or eliminate the problem I need to dramatically decrease Contrast and Brightness on the PJ, which makes the image unbearable to watch. My theory is, that because the W2000 is actually a better PJ (better colours and contrast) the glasses simply cannot distinguish between the red DLP flash and the actual picture; the sensor is somehow overloaded. While the W1070+ was a great PJ for 2D we always thought the picture was too dark in 3D, but on the other hand the glasses could actually cope. If I "replicate" the image on the W2000 to look more like the W1070+, the problems are drastically reduced. But that's like putting a Suzuki engine in a Ferrari. Sure, it will drive, but not very well.
I've read about different "fixes" for the issue, like putting tape on the sensor or blocking parts of the sensor, and trust that I've tried everything, but with no succes.
So in other words: yes, the "G05's will work on a dark 3D image and may
work on a bright image, depending on what model you have. But I certainly wouldn't recommend them if you, like me, prefer a 3D picture that actually looks close to the 2D picture. Also, looking at other models out there I see some state the glasses to have a 1200:1 contrast ratio, and the G05's are only 750:1, so I have a feeling they make the picture even darker.
As we will be shopping for new glasses, it would be interesting for us to know if anyone with a W2000/HT3050 has good experience with anything other than the Benq DGD5 glasses, which supposedly should work great.
