I bought this product thinking that the costs were not exorbitant and that I would probably spend more time trying to put it to buy it from Amazon.
And to my surprise, after watching a tutorial on Youtube (I searched myself because it receives only a manual in English / Chinese) laying took me this sticker (cleaning the MBP pass sticker on the transfer film and laying the sticker on the MBP) less than 4 minutes flat.
Application tip: get yourself a credit card or another card to rub (D & CO Damido Touch ^^)
So 5 stars for this product ;-)
