Summary: I consider this product a well nice done item for work. I use it with a lot of light on the room and the image is clear. the resolution is exellent and my students like it too. I don't see any problem with the epson ex21. it is light and the design is cool. I recommend you to try it.
Summary: The image this projector emits looks very good. I use this to watch movies at home, although the image quality is not the greatest when the screen gets larger than 7x7 feet. As long as the image doesn't get too large, the projector is amazing.
Summary: This item came through scratched as was advertised. However, it works great! It turns out that all "lumens" are not created equal. Since this device is LCD-based, it works just fine in ANY kind of light. In fact, the first slide presentation was done is a large room with bright light and there was no problem seeing the slides. I would definitely recommend this projector for anyone who needs a unit that will work in all kinds of light.
Summary: I desperately needed a good projector for my classroom. I needed something with high resolution but with a lower price tag. This projector fits all my needs. It works well in a classroom setting with vibrant colors. My only gripe is that I cannot plug speakers directly into the projector. I have to use my laptop in order for the sound to play loud enough for all of my students to hear. Other than that, it works like a gem and I am very pleased with my purchase.
