All in all, recommended, but at cost-conscious consumers not without alternative
Update June 27, 2013
Unfortunately, after only a few months, the pressure of this sticker has faded completely. In particular, the red surface is completely faded, so the effect of the label is significantly restricted. If the price is not pleasing !!
[The sticker is only 2-3 hours a day exposed to sunlight and must actually endure]
