You get what you pay for. This is a cheap screen that won't stand up to everyday use. The vertical edges curl in slightly (which distorts the image), and the retraction mechanism failed completely after about 18 months of use, leaving the screen fully submerged. On the plus side, it's really cheap, so there's not much of a waste. It's also one of the smallest screens on the market and may suit your application better. But if you can, take something better.
