Glue holds very well, is now two months since it and yet no problems. The luminous efficiency / reflection is excellent.
The price, however, is quite high for a location luminous film, in my opinion. For the price I would have expected at least two layers, so it was enough just for the stroller. Because you want to be seen on both sides and also from the front, yes, because you need not stop just a few stickers.
However, So really recommended, you should if you want to paste something else than a stroller would rather buy two.
