The Laptube notebook riser is a notebook stand designed to promote air circulation under your laptop to help prevent it from overheating.
Laptube distributor, Anyware, say unlike most other risers, this product lifts laptops using a minimum of surface-to-surface contact meaning air can circulate beneath the PC allowing for cooler operation.
Apart from the safety angle, Anyware claims the Laptube riser will elevate your notebook to a more comfortable typing angle and improve keyboard vision, and access. It is also endorsed by the Australian Physiotherapy Association.
The Laptube can expand to accommodate up to a 17 inch screen.
