This stand is a decent stand. It is tough and seems to be built well. The metal seems of good quality for sure. However, the stand has a big down side in regards to its function. There is a support strut that goes across the top of the stand. Well this pretty much rules out the chance of installing any 1u rack device. You just cannot avoid this strut. So your robbed of basically the top 1u slot. The next thing that robs you of another 1u is the fact that the stand is too low to allow the bottom 1U space to be filled. As others have said this stand is more like a 4U.
I guess it's down to poor design that two 1U slots are made redundant. So be careful in your choice of stand. Luckily there was no great urgency for me to have 6U, I just chose this stand for the extra space available if I need it perhaps in the future.
One other thing, which is not a big deal, but it would have saved some time. There is no guide on how to setup the stand. It is straight forward but a simple diagram would have helped. Must things come with set up diagrams, it's not a big ask to have had one supplied. I had to go onto the website again to see what the stand looked like so I didn't install the strut and the rear bar in opposite positions.
Performance wise the stand holds up well. It seems quite sturdy and so long as it's not abused it will hold your rack gear no problem. Obviously it will not take a huge 4U rack PA as this would just be too heavy. But it will hold your 1 U preamps and EQs and noise gates with no issues and it sits very stable on a flat surface such as a desk or cabinet.
