Example input: These are junk! Both bulbs have burned out within a two month period!! I cannot believe that this company can be in business with such poor quality. I have used infrared lights for my ball python for many years now and I get a varied range of months from a bulb, but I have never gone through two bulbs in a matter of two months! I am very disappointed.
Example output: 1
Example explanation: The user seems very disappointed in the product. Because the bulb they ordered has been burned out earlier than usual. So, he gave 1 star to the review considering it extremely poor
Q: Product was five stars, shipping was 0. I really hate to score them down because of this, but I had to spend a total of 1.5 hours on the phone with LaserShip over the course of three calls because they would not deliver a box of just mentos without being signed for. I almost had to request a refund because I was about to be required to drive 30 minutes to pick this package up at the shipping facility. I'd only buy from this vendor again if they switch shipping services.
