One example is below.
Q: 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.
A: 1
Rationale: 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: Darkening effect went out once during use right in the middle of welding. (No, that wasn't scary at all *sarcasm* ... and a little blinding). The screen does not work at all like it should. I find I have to hit the top part just above the screen most every time I use it. The screen will flicker before coming on. Sometimes it will release back to normal visibility. Sometimes. If it doesn't ... *whack!* to get it to stand down. The battery compartment has come apart along the top as the battery cover is a severe PITA to remove. (Removed battery to check it to make it wasn't dying and causing the problems). Save your money. Get something better
