Just got one and spent the afternoon trying to get it to fit where my previous non tensioned screen was (inside an MDF pelmet) and failed miserably.

Be aware that tab tensioned screens are wider than the viewable width due to the tensioning part (approx 4" each end if mine is typical). I hadn't allowed for this (no dimensions on the website in my defence and for some reason I thought the tensioning bit went at 90 degrees to the screen backwards).
They can't be adjusted for height, so you have to accept the drop as it comes or have it made to order (like mine). If they make it even slightly too long (like mine




) then you're stuffed (like me



) with a screen that won't fit in the space you've got for it. Looks like I'm going to have to either rip down the existing pelmet and completely rebuild it and find a way to gain 1" or so height so that the bottom doesn't hit my equipment cabinet (that can't easily be moved).
So in short, yes they are less likely to wrinkle unlike non tensioned which will eventually wrinkle to some degree, but make sure you treble check your measurements and be aware of the extra width beyond the viewable plus border width and try not to have furniture that will restrict the drop.
