Query: Kinamax FAN-NTP3 Business Notebook Cooler Pad

This item needs to be rated as to what computer it will actually work with. We have tried it with a couple of different brands of lap top computers and found that it is very difficult to impossible to keep the computer from sliding off of it. To say the very least I am very disapointed with this cooler!
