Purchased this sleeve to fit an Acer 5735, which is approx 15" x 10" x 2" (15.6" screen). Didn't want a 15.4" - too small, or a 17" - too big.
This fits the Acer snug lengthways and has about one inch free space widthways, which is actually handy for picking the laptop up.
Having looked at loads of these I was pleased to finally find a 15.6" version at a great price (£11.99). Its made from wet-suit type material and protects against knocks and scratches, not sure about dropping - hoping not to have to find out.
The description shows a release date of mid-May, so I pre-ordered it, but its arrived already!
Only four stars as would prefer it to be completely snug, but I don't think I'll find one...
