Have had these stands for a while, and, well, they pretty much function as they should!
Had a couple of Presonus Eris 3.5 mounted on top of them and it was fine, as it elevated them to a proper height. I have to admit this isn't the most visually appealing piece, if you're aiming for aesthetics. On the other hand, functionality wise, it pretty much does what it has been set out to do!
