I have now have this keyboard skin for almost 12 month and it be go strong . use to have one before it that be more expensive -lrb- $ 23 , from a better known brand Moshi -rrb- , but my old one just look horrible after a while -- shiny and stain on the key , protect the keyboard underneath but look embarrassingly filthy itself , soon become warped and out of shape whenever crinkle . this dirt cheap alternative do not look embarrassingly dirty -lrb- perhaps due to the black key ; the other one be transparent -rrb- and be still shaped flat like the day i buy it ... I order it a year ago come June , and have not have a day of dissatisfaction ... I can imagine have it for a long time in the future .
