Review on 👓 High-Quality 2X EPSON Compatible 3D Active Glasses RF Pro Scarlet Heaven for Epson Home Cinema Projectors (750HD, 2000, 2030, 2040, 3000, 3020, 3500, 3600, 4030, 5020, 5030, 6020, 6030) by Travis Caminiti

I bought these glasses for my Epson Home Cinema 2040 projector. They have a good design, are comfortable to wear and are very light, weighing only 32 grams. 3D is superb. And as other reviewers have said, the storage box that comes with the 4-pack is a really nice addition. They can be used with a 3D TV via Bluetooth, or with a projector or emitter via RF. I've searched the internet to find out how many pairs of glasses I can connect to my Epson projector and couldn't find the information anywhere. So I emailed Hi-SHOCK (via Revain) and asked if they could tell me. They could, and here is their answer. "Normally, around +50 points shouldn't be a problem. Since it's an RF signal, the quality is really good and it's easy to connect multiple devices.” Excellent! And I ordered two 4-packs. Something that isn't on the Revain website is that Hi-SHOCK is based in Germany. A couple of points on that. First, I emailed the question to Hi-SHOCK twice, both times around 10:00 PM CA. And both times when I checked my email the next morning, there was her reply. Germany 9 hours ahead worked in my favor. And secondly, as it was being shipped from Germany, the item arrived a few days later than the Revain's estimated delivery date. For me it was no problem. I wholeheartedly recommend Hi-SHOCK and this product without hesitation!
