Has definitely helped in stopping me leaning forward all the time to view my screens, but moving the screen up and down along a y axis is not that easy; you need to push the arm back, which means your desk cannot be up against a wall. A small issue for an otherwise great product.
Easy to assemble and use.
Easily understandable manual for adjustments on tension and positioning.
Great looking on any desk.
I am extremely happy with this product. I work with huge spreadsheets and being able to set up two monitors that are easily moveable are a great help. I will definitely buy this again for my other staff.
