Laptop stands are a great way to elevate your laptop to make typing more comfortable, but they're not exactly portable. BaseLift sticks to the bottom of your MacBook and raises it just a little to make it easier to type.
BaseLift works a lot like an iPad Smart Cover. It sticks to the bottom of your MacBook, then you can fold it up to lift your MacBook just enough that typing is less cumbersome. It's not as elevated as most laptop stands, but it does its job well enough.
Because it sticks to the bottom of your MacBook, it also works to dissipate the heat that comes from heavy usage. It has a pretty sturdy feel to it, so even if you throw your MacBook around a lot, it seems like it will continue to stick on and work just fine. It does add a little weight, but it's not that noticeable after a few days of use. The BaseLift works with all the various MacBook models, from the 11" to the 15".
