I purchase this skin in both blue and green to replace a red one I buy last year . the new one actually fit my 2-year old Macbook pro unibody better than the original ! it do the job , and the color be nice . more subdue blue when I do not have my key light . the fit be great , and there be a definite lack of dirt and other nastiness get underneath . the only potential drawback be a buildup on the cover that can get on the screen . keep this clean and be aware of the need to change it out when it get grimy be a must . however , it be so affordable , no biggie to get a new one when need .
