Title: No need to boil or leave in the sun
Review: This works very well, it even comes with a strong double sided tape strip to stop it from moving on smooth floors.There have been lots of comments about it not lying flat, with some people resorting to boiling it! This is not necessary. When the strip arrives, simply take it from the box and roll it back up in the opposite direction. Leave the box until the next day. The strip then lays flat. I left this box in a 72 degree room for 24 hours and it made the strip flat. No boiling, and no fuss.
