Problem: 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
Explanation: 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.

Problem: I purchased this product as I thought it was a new keyboard. As this is the normal price for this keyboard on other sites. I received the keyboard and the packaging was CLEARLY re-sealed. Normally I would be like "meh it was probably a quality check or something". I took out the product and there is sticker residue on the keyboard next to the Corsair logo. There is dust EVERYWHERE under the keys. There is gross stuff on the bottom of the keyboard that could only be described as "old desk gunk". I have purchased products advertised as "used" that are in nicer condition. The replacement they sent me is also opened and used. How does this even happen?
Solution:
negative
