After having issues with a couple of pull-ups from a competitor I decided to go with Duronic's FPS60/43, and I'm so glad I did. I live in a small apartment, and this screen is the perfect solution for my living situation.
There are no obvious waves in the screen unless you get right up on it and look at it from the side. There's almost no bowing on the sides of the screen, which is a problem with some pull-ups. No rips or dirt or oil smudges, all of which I've had issues with in previous pull-up purchases. The screen looks bright, and projected light is evenly distributed. Build quality is all around very decent. The pull-up is packaged with a user's guide, and a case cover where the whole screen fits into to prevent scratches while in transit.
After a lot of research and experience with other screen makers I think I can say with some confidence that if you're in the market for an affordable portable this is probably the best out there.
