Query: AWFUL! STAY AWAY!

I recently got a Wormlight Advance(purple, but not clear purple) and this thing is really a horrible piece of plastic. It blocks the screen and the light leaves a bright dot in the middle of the screen so it's harder to see. If you're riding in a car and you need a light, get a car with a car light. When you're sitting at home, sit by a light. Do anything, just don't waste your money on this.
