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 Stephen Cernatescu

I bought two pairs and they both fit the Epson 2040 projector. These glasses are quick to pair and sync. The images are sharp and clear. The battery lasts quite a long time. The battery is less than 20% empty after 3.5 hours of continuous surfing. There was no continuous blinking of the light, as one reviewer said. The goggles really do darken when turned on. Here are a few things I would like to improve. These glasses are definitely darker than the Epson RF 3D glasses. I wish they were a tone lighter for clearer viewing in ambient light. There is a slight crease on one of the temples which causes the lenses to move sideways when worn. This could have been caused by the shipping process as these steel mailboxes get very hot at over 100 degrees. Suggestion, aluminum bags or something to protect the goggles from extreme heat so the plastic doesn't bend. The last thing I wish the charger was micro USB and none of those connections. Final Thoughts. I like these glasses very much. They are affordable and get the job done easily.
