The grey bar is supposed to make it easy on the eyes but it catches glare from overhead office lights. Also the bar sticks when you get to the curve making it take longer to move the bar. It is still a great improvement from the 8 yr old holder I had and it is quite sturdy.
This is great for holding a number of papers without them falling all over the place. The curved body is a plus. If you need to purchase one of these it's worth the money.
