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!

Ex Output:
positive

Ex Input:
These don't work. Don't pay any attention to all these good reviews, they're most likely fake, because out of this pack of 20, I've currently gone through 6 or 7 just trying to find ONE that works. These do not work.

Ex Output:
negative
