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: I'm unsure why this vendor is effectively charging 1/2 the price of many other sellers that don't even include the weather stripping. This is the exact same product, same manufacturer, packaging etc. It does a great job so I'm not going to question it too hard. A suggestion to anyone that wants to reinforce the sweep so not have to rely on the adhesive alone; use a small wood screw drilled through the upper part about an inch from the edge on both ends of the sweep. Space a couple more in the middle. PURELY OPTIONAL - Dip or brush screws with white paint BEFORE installing them (if you do it after it is really tough not to have any spots of over-paint and your white paint won't be a perfect match so it will show). Also make sure to use a flat headed wood screw instead of round head for cosmetic reasons as well.
