Query: Useless for a STAR-BREAK type chip.

I bought this item for fixing a small chip (less than half inch) on my windshield. It's a STAR BREAK chip. However, this kit didn't work for this type of chip. Due to the physical press when I use the kit, the crack even enlarged to 1.5 inches. I was very disappointed and decided to look for local auto glass store. If you have a STAR BREAK chip, this kit WON't help you. BE AWARE.
