The good:
Tilt and front-rear shifts on the monitor plates are really nice add-ons. I placed my (16 kilo) monitors above my 3 computer screens, tilted and shifted the plates to taste and voila, I can now sit at my computer, having the monitors pointing down at my ears with a clear field of view.
The bad:
If your woofers are large-ish you WILL get noticeable vibrations traveling through the stands to the floor. I guess filling the hollow tubes with something heavy will mitigate that somehow.
There's a wobbliness to the system, but that's a tradeoff for the small footprint. The situation could be alleviated if there was a way to adjust the tripod supports, but there are only plain felt pads to be seen there.
These felt pads are easily compressed by the weight of the monitors and stop being useful at providing meaningful vibration reduction.
I will DIY something in this area, current situation is not good.
Thomann should also make it easier to see if stands are sold single or in pairs, this info should not be buried in the details but visible in the main "studio monitors section".
