Overall these glasses are great. The picture quality through them is beautiful. They are large enough for most people who need to use prescription glasses underneath. They charge easily with a USB cable. They turn off automatically after around 5 minutes on not being used. You can even tune these to get most of the ghosting or crosstalk out, if you have any at all. (My Optoma HD3300 came with the emitter needed to work with these glasses, and this enables you to tune them, also comes with the Optoma HD33 I thought I would try some DLP-Link glasses, but I'm so happy with the image quality with these, I'm not even going to try it. They leave no funny tints of green or anything like that to the image projected (I read someone complain about this with other glasses). I only paid $79 for these on Amazon, so I would wait for the price to come back down from $99 (I believe $99 is over priced!)

My only complaints are: The button to turn them on is VERY hard to press down. This should have been just a simple press and not have to jam it down so hard (I'm a little afraid of breaking them). And, where the lens is so large, there are reflections showing up in the lens, from anything that is behind you. If you have something bright or white colored behind you, you can see the reflection inside the lens. Both definitely not deal breakers to me. I plan on hanging a little bit of cloth around the frame to block the reflections. I like to doctor stuff up, to work the way I want it to. I do tend to be a little too picky, but It's my hard earned money, and I like to tell the truth, and I do praise the image quality of these glasses!

One star less than perfect because of the "on" button is difficult to push and seems flimsy. That said, RF is the way to go for 3D glasses. No lost connections... no fear of moving your head (like with many IR DLP glasses) and disconnecting. Fits VERY comfortably over my regular prescription glasses. Holds a battery charge well. They do NOT come with any kind of manual or real instructions on how to adjust them. They are almost identical to the Monster RFs, and the adjustments are similar. Optoma needs to include the manual and/or at least post it on their webpage! Remember you can't mix and match types of 3D glasses with your Optoma HD33/HD3300... you need to choose DLP or these RF... to me it is a no brainer get the RF....

After much debate on pros and cons of DLP LINK ZD201 and Optoma RF, I have come to decide that i definitely prefer RF's hands down. way more comfortable, a lot less bulky, no inverting or re-sync problems at all. My whole family hated the DLP link ones. My son could not fit the DLP links and wife just did not want to watch 3D at all. but RF fits him and her perfectly and son is five. He likes to move around a lot and run up to the 120" screen to get into the action. Watched Imax 3d Deep sea and he was 2 feet from the screen petting the fish. Funny. Glasses never loose sync. It's like wearing sunglasses. I can seriously wear them for hours. I actually calibrated the HD33 to give me better contrast to match DLP link Quality which it seems to have an advantage over RF. Not an issue with me anymore. Love the RF's. I have two, one for wife, son and I am going to order me one very soon. Yes the build quality feels like it could break but they went with lighter materials to really, in fact, make them more comfortable. Comfort to me is much more important. Watching 3d needs to be fun and enjoyable. Not fighting with heavy, bulky, uncomfortable, unreliable connection to projector glasses. If you take care of the RF's, then this is really not an issue at all. Okay the power button issue. Yeah, when I first got them i had a hard time pressing the button. Took a few times but finally you learn how to put just the right amount of pressure and really not an issue now. Wearing RF's I call 3D freedom and finally enjoyment for the whole family, including kids.

Want my 3D calibration settings to match DLP link in contrast, go to AVS forum under "Digital Projectors under $3000" the click link for HD33. Start at the last page and work your way backward. Will see my posts as CVH. RF's are the way of the future.

Optoma Technology BG-3DRFGLASSES 3D RF Rechargeable Glasses
Despite the hefty price tag I reluctantly ordered 2 pairs of glasses for my fairly new projector (Optoma HD33). While having checked out 3d TVs at Best Buy and comparing Panasonic, Sony, Samsung I was never "blown away" by the quality of the 3d, perhaps it was the content or the viewing environment so having 3d on my projector was only a bonus. On to the glasses:

Setup - simple. Thats the best way to describe it, upon opening the box you find the glasses in a fairly secure enclosure (which I will use as its storage while not in use) and a usb cable for charging purposes. As soon as I opened the boxes I charged the glasses via my laptop for a few hours.

Use - again, very simple. After starting up Avatar 3d on my bluray player I simply pressed the power button on the glasses and within a few seconds the glasses were synced to my transmitter (plugged into my projector) and the image on my screen was perfect.

Quality (of picture) - great, and I was not prepared for how impressed I actually was. Going into this I swore I was going to regret this purchase because I was not sold on 3d tech. I only watched a few minutes of Avatar but I was impressed with the color/contrast (I was expecting the glasses to effect this the most). The 3d was really impressive with the amount of depth that was showing (I did see Avatar in 3d in theaters but that was quite some time ago so my memory is useless here to compare the two). I quickly checked out Lion King 3d and Cars 2 3d and while not as impressed with the 3d effects the quality of picutre and 3d when show was still great.
