It's neat, it's functional and above all, it's cheap! Great for flipping eggs without damaging expensive pans.
It's heat resistant up to something like 180 degrees centigrade, but it will of course melt if you take it over this or leave it in the pan.
Why or how there are one star reviews I'm not sure, it would probably cost more to drive to the shops than it is to have this delivered! If you treat this with care and are aware of cooking temp's, you'll be fine.
