Question: Is there any "Hot Spots" on the screen from the projector light, or does the screen diffuse the light? I want to use this for film to DVD transfers.
Document: I bought the portable screen to watch movies at home with my mini projector. It's super light, the perfect size and easy to carry. Loving it!
This projector screen is perfect for what I do. It's extremely light weight and portable. It's very easy and quick to set up...takes all of 30 seconds. Best value out there! I would recommend this screen to everyone...and have!
I wanted a tabletop screen, and I got exactly what I wanted. It is light to carry, pretty easy to use. My only problem was coordinating pulling the feet down and the screen out, but probably that would improve with more use by me. I used the screen for public presentation by laptop and the image was plenty wide and easy to see for the meeting of 30. I wish it had a strap for over the shoulder carrying but otherwise the design is great.
This screen is light weight and easy to use!! The strap makes it perfect for the mobile presenter! Buy it!
I teach classes all over the southeast. I have a big screen for larger rooms but this is perfect for smaller classes. It is so light and easy to set up.
Easy to handle, use and carry with you at every place to make a presentation. Good companion for my Dell MZ110 projector.
I give presentations away from home and this Epson portable projection screen is perfect for this purpose. It's light in weight, folds into it's own vertical pillars which snap together to become it's own carrying case. This is a really great product.
Easy to use. Nice and durable. Light weight. Sturdy product. Works well for brief meetings as it's easy to set up and take down.
Very easy to set up and take down. The only draw back is the length, but no getting around that  if you want a smooth screen.
Nice size, easy to carry & set up. Folds into a self contained box.A little tricky to use at smaller than full expansion. A nice adjunct to a portable projector on the road.
