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.
Output: 1
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

New input case for you: The design of the fan is great. 3 speeds. Easy to operate and not only can you wear it around your neck you can use it as a small desk fan. However, after a few weeks one fan stopped working. I tried a few things but couldn't get it to work. I emailed the company and within 2 days I was given a full refund. So, in my opinion, if you're on the fence about buying these there's some peace of mind that the company will do the right thing if you are not satisfied. I used my refund to by another pair.
Output:
4
