I absolutely love the SideTrak. I was able to attach it to my laptop cover and I love that I can remove it when I need to. This is especially helpful when I have to go into exams - I don't have to worry about having the extra monitor when I don't need it. I use it especially when I work on legal clinic items where I need to have multiple documents open. It helps reduce the constant switching between internal screens, and now I can just move my eyesight from left to right. Even though it is pricey, it has been worth the investment. The price tag justifies its utility and I couldn't be happier.
