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: Great value for the price. Easily cuts up herbs. Love that the case is also the cleaner to get the bits out of the blades. I had basil and chives readily available when I got these. Chopped up so quick! Sooooo much easier than my knife! And my husband says "safer for me too." Highly recommend this nifty gadget!
