Input: Consider Input: I'm so glad I stumbled across this product, because it has seriously improved my WiFi speed. Using it on an older laptop , I noticed that WiFi speed was faster than the built-in WiFi . I later tried it on an older desktop and it was very fast as well. An excellent product!

Output: positive


Input: Consider Input: Shipped out on time and arrived early! Very neat package and perfect invoice/product. Product package was sealed and when opened, product was fresh. Good Quality product!!

Output: positive


Input: Consider Input: 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?


Output: negative
