Easy to install. I have reattached several stickers that I had not positioned (2/3 posed some through in haste), no traces of adhesive left on the keys and grip is the same as for auquelles keys I n ' have not touched. The stickers do not cover the entire surface of the keys (Samsung Laptop) but covers the characters underneath.
I'm moving to the United State in a few weeks so very convenient to train and especially I can iron without worries thanks to the double French characters on the stickers.
