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.
I put a heavy 15 inch ThinkPad on it and stays firm. Solid. Can probably type on it but I use mine with an external keyboard beside an external monitor, and gets my laptop to the right height. The support notches are small and rounded and low enough in the center so that they don’t get in the way of typing. generics have the notches higher and to the side where your arms have to be raised to avoid the notches to type on them. Good stand. Not an ultra portable pack in the bag kind of stand. But good for multiple extended uses around the home, living room, kitchen a fixed workplace or office. Also raises your laptop camera to correct eye level for better zoom or e learning sessions. This design doesn’t take valuable desk space away from you and you can type closer with a keyboard underneath or store notes below. Good accessory to have around the house like a screw driver or your own tool box. Once you have it you will know why you had it in the first place. Not a throwaway kind of workplace accessory. Good for your back and better ergonomics.
