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: I wanted to be really excited about this whiteboard mat. But when the order arrived there were no pens or eraser like it was advertised. The tube the mat arrived in was not sealed on both sides and there was no sign of the eraser or pens in the box. My guess is the pens and such fell out before it even got into the shipping box. Hopefully Expo pens don't stain the mat I guess
