I searched for several months for just the right laptop trolley. I work from multiple locations and my computer, files, tablet, calculator, and pens all fit in here conveniently. The hard shell is waterproof in the Midwest winter weather. The spinner wheels glide smoothly and have a full 360 turn range. Then there is a roomy section for overnight wear, or gym wear. I highly recommend this piece. Did I mention how beautiful the blue shell is? I am so pleased with this purchase.
