The product is fairly good, but i am not completely happy with it. The bar is solid and sturdy, has good markings on it, and displays ORTF or XY angles for convenience. The knobs for angle at the base, or distance between the mics are solid and work great. They are easily tightened and stay that way.
The only thing that is not working as i would like are the knobs to tighten/fix the rotation of the microphone. you really need to use some force to tighten them, otherwise it will become loose quite easily. But as there is not much 'feel' to the tightening, it is a bit of hit and miss. Of course you will run into that while recording...
I think it would have been a nice feature if they included a small adapter on the threads so you can adjust the height, allowing two pencil condensors in XY to cross each other at the endcaps. I use two thread converters from K&M for that purpose. Cost of that is only a few euros, so why not include such a simple thing...
I still use the product, since its doing what it should, but i do have some "moments of frustration" when the rotation is slipping again... Love/hate relationship i guess.
