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: 1
Why? 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: I gave this 1 star because this particular probiotic has caused nothing but issues for me. Since taking it the last few weeks at only 1 pill a day instead of 2, I feel constantly on the verge of some type of cold, got a weird superficial ear infection that I've never had in my life and now having weird rashes appear on my face. The only thing different I've been doing in my day to day life is taking this probiotic. It may be good for others but definitely would say to stop if you have unusual issues because this is in no way normal for taking a probiotic.
