When doing assignments tests and research papers, i've experienced some aches on my back and shoulder areas. Which is why i started using a laptop stand. This one here was kindly sent to me by the company Lention. it's made of a very thick and sturdy aluminum. This one in particular sticks out for its adjustability.
