I like very much the high quality of the sticker and the effect it generates.
I do think though that the little tongue in the lower left corner is a bit ugly. I understand that it helps removing the sticker, but I don't need to change the sticker so often. I would prefer making it more difficult to remove than have the tongue always on. I have even thought of cutting it altogether.
Another drawback of the tongue is that it makes it easier for the sticker to peel off. That's what happened to me. It peeled off two days(!) after I placed it and it gathered dust and now the edge of the sticker is on the air. Not good at all. Thank you.
