The main benefit to this large and impressive screen, is just how easy it is to use. Putting up takes literally 10 seconds:
1) Twist out the 2 feet.
2) Un-click the 2 catches.
3) Open the lid.
4) Pull up to your desired height.
5) Done!
The mechanism makes pulling the screen up easy and smooth and what isn't mentioned in the description is that you can stop at any point, and the screen stays in that place, so you can adjust the height as you see fit. It's tall enough so that you can stand it on the floor, or on a table for extra height.
The first time I used it was in an industrial unit with the big strip lights on and the noon light streaming in through the windows, yet the display was bright and easy to see, so I was very pleased with that.
At the time of writing, mine is the first review of this 80 inch product, but I believe it to be the big brother of the 60 inch PCP60MM, which gets solid 5 or 4 star reviews which is what helped me decide to buy this one in the end, as I don't normally buy products with no feedback.
EDIT: I had a problem with the handle, which broke after a few uses. I contact Duronic and they immediately offered a refund or replacement without quibbling. I opted for a replacement and a new screen was sent to me within days, on a day of my choosing, and the courier collected the broken one. Altogether very good customer service!
