Due to the many positive reviews and I have bought this product. Visually, the product looks very high and stable, the devil is in the details. Since I built the desk at home fix, and not extremely burden, it fits perfectly. The holder of the edition you have to tighten already very strong, so slightly heavier note books or folders they can not twist. However, the screws will get not so robust. Anyone who wants to go on tour with it and must often up and take down, I recommend to switch to higher-quality branded products. For permanent structure at home, it is sufficient anyway.
