Crystal Case - Sony Ericsson S500i

I HAD THIS CASE FOR LESS THAN TWO WEEKS AND NOTICED A LITTLE CRACK, BY THE END OF THAT DAY; THE CRACK HAD GONE RIGHT ACROSS THE CASE. THIS HAPPENED TO BOTH THE FRONT AND BACK. I AM ABOUT TO ORDER ANOTHER CASE AND THAT’S ONLY BECAUSE IT LEAVES MY FANCY PHONE ON DISPLAY, INFACT THAT IS THE ONLY GOOD THING ABOUT THE CASE!! I WILL TRY TO BE MORE CAREFUL WITH THE NEXT ONE BUT THE DURABILITY CLAIM IS FAR FETCHED.
