Sumdex Impact Guard Laptop Sleeve any good ?

[jurassic]

Hi !

I need to buy the best notebook insert sleeve there is for my wifes laptop... I have heard many good things about Sumdex Impact Guard PUN series:

But I need some good advice here, since i have bought other sleeves in the past (non brand in Office Depot) and they are really junk...

Does anybody have experience with Sumdex Impact Guard at all ? Does it really absorb shock as they claim ? Pricing is good as i can see, but i really want the best

I am looking to fit my wifes IBM T42

Any other suggestion ?

Thanks
