This is my second orchestral stand, which looked much the same as my one from another manufacturer and retailer.
The Thomman orchestral stand is very solid, and just right for thick music books, digital recorders and iPads along with sheet music.
However, although the upright pole is straight, the head support is not level! The shelf is not at a true 90 degree right angle. This means that when I went to turn a page in one of my music books, the page caught on the shelf and ripped free from the spine! The finish on the shelf is rough and poor, adding to page damage.
I am sure that I just got a 'bad one' so this might not be true for all of them, but quality control should be better.
I am left disappointed.
