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: There are some design flaws like the ramp's black rubber goes loose easy, and the rake gets stuck at the dirt bin on manual function, But otherwise, The Automatic function works well and does it's job..... The Plus is that it saves me time in manually cleaning the dirt as opposed to the non automatic litter box.... For some, The flaws might be a big issue, but these does not bother me much for as long as the main automatic function works as intended.... If ever this machine breaks, I definitely will try the other brands next time....
