Lapinator

- Silly name, great product.
- I've had one of these for a couple of years now and can't imagine using a laptop on my lap for any significant amount of time without one.
- It's very comfortable, really does a great job of shielding you away from the heat, and fits nicely in my laptop backpack.
- I have a Dell Inspiron 8600 15.4" and it fits fine on the regular lapinator.
- I also own similar products: lapbottom, coolpad, and laptopdesk. Lapinator is by far the best one.

Highly Recommended.
