Question: Can you lock it in place at 46 or 48 inches? My table is not 50 inches wide.
Document: It is well built, not heavy, easy to open and close. Only a bit too wide, if you want to put it on a table. It measures 46 in wide (considering the little stops en each side), so have that in mind.
I give lots of presentations in all sorts of locales. Sometimes I'm in a private area of a restaurant where there is no blank wall space to project. I ordered this mini screen to be able to have in my car at the ready for such occasions.It is super lightweight and easily carried even when you're lugging other equipment. Opening and closing it is a snap; and when it's open, it stays open.It's the perfect size to place on a table and project your PowerPoint.
Pros:  Sturdy and easily portable. Excellent reflective properties that make the display from a 500 lumen LED projector quite visible in a room with low to normal lighting.Cons: When fully extended it is wider than many tabletops (such as my dining room table). It is supported only by the feet, and the scissor action support arms will try to retract it unless fully extended and held in place by the friction of the feet on the table top.
If the roughly 50-inch diagonal screen works for your purpose (and it does mine), then this should be a fine product for you. It's sturdily made, but not too heavy. Good quality materials, simple in design, works right out of the box, and is reasonably priced at $60-70. I'm happy.
Easy to handle, use and carry with you at every place to make a presentation. Good companion for my Dell MZ110 projector.
Slide it open, place it where you want it and start watching. Well made, easy to carry around and it sets up in 2 seconds. The product quality and the price make this a great deal.
First off, I also own the big brother Epson ES3000. I purchased this for it's compact form factor and lightweight. However, the 50" diagonal measurement only applies to 4:3 aspect, if you are using it for 16:9 the measurement will be smaller than 50", there will be unfilled area above and below the screen, unlike the ES3000 which measures 80" @ 16:9.
GREAT, but, no clasp to lock it into position?? Why???? Such a good product in every other way. Oversight? just dumb. So unless you have a hard slick surface for the rubber feet to sort of stick to, it will collapse back into collapsed position, either gradually or very quickly.
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.
the expected stability of the product on a table is poor ..  it bents foward cannot make it stay open
Answer: yes
