Query: Eh...not so good

I bought this 3 months ago, always kept it on the lower oven rack, not on the bottom of my gas oven. I hand washed it when dirty. Now it is cracked, and a white color around the cracks, it has holes in it, looks horrible, and it's no longer protecting my oven floor. It's getting tossed out. The concept is good but it's a flimsy product, not worth the $$.
