Example: 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 solution: 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

Problem: Product took a while to be delivered. This may have been due other items from different sources combined with this one in the shippment. Instructions were not the easiest to follow but with multiple video sources and repetitive trial and error I got it done. All heads were clogged. Persistence yielded success.

Solution: 4
