Query: Really helps prevent neck problems

I bought this to elevate my laptop screen as I was having neck problems caused by years of looking down at my laptop. This really solves that problem as it brings the screen up to eye level and improves my sitting posture. Also, I like the angle that I now have for typing as I can see the keyboard more readily at the new height and it's a comfortable angle for typing (which was surprising). It's not as neat looking on my desk as the small laptop alone is, but it's really an important improvement for my neck and spine posture and health.
