At first I was a bit sceptical if I should invest this amount of cash into something (as I thought at that point) insignificant as monitor stands. But while doing my research I came to conclusion that for my purposes and limited space there's nothing better than IsoAcoustics. Price felt a bit high (like, come on, it's just some thingy to put monitors on it), but this item is high quality.
No sharp edges, feels reliable.
It isn't absolutely rock-solid when assembled, there is some movement if you push it, but that's the point.
Anyway, everything is stable and I don't fear that my Adam A5x will fall down. I tried stomping on the floor near, kick table etc etc - nope, all fine.
Worth every penny? Well, probably. Still want the price to be a bit lower, but I guess that's the best it could be. Good things don't come cheap, right?
