I needed a monitor arm for my 490 Pro 49 inch beast, that fitted a secretlab Magnus Pro desk.
I took a gamble, as this was a quarter of the price of anything IU could find that I knew would support it and fit on the desk.
I won the gamble.
This is good looking, very easy to fit and adjust - altogether I could hardly have asked for more!
My only grumble (but this is the same for most monitor arms I've had in the past) is that fitting the cables through the cable covers is fiddly - it ended up being a two-man job once the monitor was attached. Perhaps I should have fitted the cables before the monitor!!
Oh - and it has two USB ports in the base! I mean, this was something I didn't even know I wanted! But it is so convenient for shoving in that USB drive or charger cable!
Honestly, my whole experience with Prism+ has been great - I was wary, but wouldn't hesitate to but from them again.
