This is a really nice clear cover for the Samsung N120 Notebook computer. It is very easy to fit - simply clips over the existing case, and is easy to remove too. The two part case has holes where the all the air vents and access ports are, so nothing is covered up. It does not appear to make the laptop run any hotter than usual. It gives the Netbook a great glossy appearance too!Note that this is an external case and is NOT an LCD screen protector or keyboard protector.Given the low cost of this cover it's a steal! One added advantage for me was that one of the rubber feet on the battery had detached making my Notebook a little wobbly on a flat surface. No big deal, but a bit annoying. This case immediately solved this issue as case thickness is the same as the rubber feet at the battery, so bingo - no more wobbling!
