Review (5/5): Great for peace of mind.
I'm that person who always forgets to turn off her flat iron in the morning and doesn't remember until getting all the way out to the car. Then when I go back inside to turn it off (making myself late for work), 9 times out of 10 I find that I did turn it off but I had forgotten. To solve this problem, I purchased this mat along with an outlet timer (one that I can set to one hour). I turn on the flat iron at the outlet and rest it on the mat. Then, even if I forget to turn it off, the timer will turn off the outlet. And just in case, if something happens and the outlet doesn't turn the flat iron off, the mat will protect the counter. (Don't act like this is irrational—I'm sure that almost everyone who uses a flat iron on a regular basis worries about this!)
If you would like to have peace of mind (and a better attendance record at work), I highly recommend this mat!
