To calculate the overall star rating and percentage breakdown by star, we do not use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Comfortable in the way it supports the laptop on the legs while seated and convenient to just use as a tabletop on a carpet, bed, or other soft surface. My laptop does have rubber feet, so I saw no issues with it sliding. Wide-enough to hold my 14-inch laptop with a small hub to its side; will hold a 17-inch, but anything plugged in may be pushed off its surface... I like the size as-is however, and would probably like it less if much larger since more to carry during travel/vacation where I more frequently use the laptop.
