Review on 2 Pack of Rechargeable Active Shutter DLP 3D Glasses for All DLP-Link Projectors - Compatible with BenQ, Optoma, Dell, Acer, Viewsonic (Black, 144Hz) by Junrey Jewel

Tested on BenQ TK850 with 100" Matte Gray Elitescreen (non ALR version)1 Lightweight RetroDepht Glasses: Pros: Very comfortable, definitely the lightest of the three. convenient for people who wear glasses underneath. - Has a button to reverse the image if needed. - Always synced with movies. - Very clear picture. (2nd place in the points comparison) Disadvantages: - has a very slight red cast, hardly noticeable. (Reason why they take 2nd place in the Sharp Picture category) - Since they basically don't have a "frame" with very sharp edges, some people might find them annoying. 2 Ultimate 3D Sky Points: Benefits: - Pretty comfortable, and still light for its large frame. - Always in sync with movies. - Best and sharpest picture of the 3 glasses in comparison. - Large black frame hides the surroundings and draws your attention to the screen. Cons: - doesn't have a button to reverse the image. So if your projector can't invert the image with its settings, you're screwed. People who wear large-frame glasses may find it difficult to fit them under the model's frame. 3 Boblov glasses: Pros: - there is a button to reverse the image. And quite violently: the synchronization with the film is often lost, especially in scenes with extreme camera movements. - In terms of image sharpness, Boblov takes 3rd place, pretty clear, but has an unusual hue that gets darker at the top and lighter at the bottom. The frame is very small, so when viewing on a large screen, you have to move your head, not your eyes. It also may not help people who wear glasses underneath.
