In terms of product quality, these protective films are excellent. They are very easy to instal and are quite resistant over time. I say this because this kit complements the one already installed on my carbon frame, the "Stranger things" version.
The only improvement I can suggest to the manufacturer is related to the film dimensions. Maybe something could be done so that when ordering the films there is the possibility to order the dimensions desired by the customer, it is unlikely that the standard cut film will fit exactly on each frame. I would be willing to pay a higher price for cutting to the desired dimensions and I think I would not be the only one, because the films are excellent and with the exact dimensions they would be a winning solution.
