when first removing the moshi clear guard from its packaging the first thing you notice is it really is impressively thin. it fits over the keyboard exceptionally well, and it certainly doesn't spoil the all important aesthetics of a fancy laptop thanks to its unparalleled transparency. being made from urethan its incredibly durably and easy to clean. for general daily use it serves as excellent protection from any general stuff, like crumbs or hairs from pets/hairy flatmates, that might try and make there way into your laptop. if you spend a lot of time just playing about with your macbook and generally always have it by your side its great. spending 20 odd quid to protect your expensive investment is worthwhile. however, if like me you spend long periods of time typing it can be a bit of a nuisance. being a student i primarily use my laptop for writing long boring essays, and i've found the additional force required for typing quickly over long periods of time can put a bit of additional strain on your hands. thankfully the moshi clear guard is easy to take off and put back on as it just sits over the keyboard. another issue is the remarks you may receive from friends for having what appears to be a latex splash guard over your keyboard, however on the plus side this will generally make them more apprehensive of borrowing your beloved mactop.
