These stands are durable, easy to build and they look good. Box is big and heavy, the corners are reinforced enough for transportation. Instruction manual information about mounting possibilities, and they come with a little wrench to tighten the screws. They can be rotated left - right and you can adjust the height. Once into the room, they are easy to set as you like - it is possible to rotate the triangle stand and platform. Below the platform you've got a little clip for cables. They feel firm and sturdy, the platform is big enough to hold bigger units to something like 6 or 7 inches monitors with little rubbers on the edges for avoiding accidental slip. With pads on the bottom they won't scratch any surface or you can use screws with spikes if you've got a rug or floor mat.
On the pros side : they are good quality, paintwork is nice, best quality & features for this price. Does the job
on the cons side : poor weight distribution - with big monitors on the last two heights which you can set give a small "wobbly" feeling. I use them with Presonus Eris E5 which is 4.63 kg and it's fine, but for something bigger I would lower the height. Platform size is ok but if you want to lay monitors on the side they will protrude on both sides. Base in the shape of the triangle may not fit in all spaces. Another thing is the lack of ability of angle adjustment to make them low and still pointing to ears.
In the end, for this price you can't go wrong with a home studio. I 'm happy with them, and I bought a second pair for my friend's birthday. I think we got good value for my money. Totally recommend it!
