I had the opportunity both variants (ISaver2 13.95 & Crumpler The Slip 17,50) to test.
First to the function,
Both cloths protect the MacBook screen in which they are located between the screen and keyboard, and thus prevent damage to the screen. They also protect the keyboard from dust and dirt when you use an external keyboard. One can use the towels also clean the screen if whoever is filthy.
Now to the specifics,
the slip has a rather soft surface that feels nice, but it is not as well suited for cleaning the screen and it is quite slippery, so its use as a mouse pad is not possible. SLIP can not wash, so he does not have a long life expectancy, in my opinion.
The iSaver has a smooth surface, he feels more a bit stiff, which has the advantage that it does not so easily wrinkled, but this should happen to anyone, you can wash in, so he will not only clean, but also his old form gets back. Due to its smooth surface and the fact that he did not slide, you can use in super as mouse pad and it achieves better results when cleaning the screen.
Conclusion:
Both are suitable for protecting a Macbooks, which is ISaver2 my opinion the better solution, because it is not only effective but is also available as a mouse pad yet, he better Dressing and you can wash in.
