Review (5/5): use hair drier to make the winkle flat, then it works better
Like many other reviewers said, it arrives with winkle as it was fold in package, which makes it not that comfortable to see outside. However, after contact the seller, i got suggestion to use a hair drier to make it more flat and seeing better. It took me about 5 min with heat mode to make it soft and winkle less. Now i can seeing more comfortably.
