Question about TwelveSouth Curve

Been using it with and old thick laptop for a while with no issue. It really depends in shape and thickness.

If the front edge of the laptop is not straight, or higher than the tip of the stand, it’s the anti slip rubber that will do most of the work from the bottom of the laptop.

If you have a thin laptop it will work perfectly.

Probably, but it was designed for MacBooks so it will be a better fit for those.
