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.
Solution: negative
Why? The user seems very disappointed in the product. Because the bulb they ordered has been burned out earlier than usual. So, it's a negative review.

New input: it worked fine for a year, except for one occasion where it just did not work....... i took the machine and shook it a few times, it magically started working again several months after that, it stopped working at all..... but there was a 2 month warranty period, and customer service sent me a check for the refund..... so things left on a happy note on another note, it's small and very easy to use, looks nice too..... neat stuff
Solution:
positive
