This notebook stand is light, pleasant on the lap (comfortable padding). Just for a 17 "notebook, but for a 18" I think it's fair. The coating is sufficiently resistant and maintains the cell in most cases. However it happens (if high angle of inclination (> 30 °)) that the PC slides. The retaining strap does not seem very effective in this case (after slopes more than 30 ° passes over the PC). In conclusion, good support, comfort and quality. Moreover it is not expensive.
