[EX Q]: 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 A]: positive

[EX Q]: Wearing everyday and overnight, this band is holding up great!!! The matte finish has rubbed off a bit and is now shiny, but the band looks and feels brand new. Many compliments. Would buy again.
[EX A]: positive

[EX Q]: This printer continues to print poorly. I've aligned and cleaned the heads, changed the cartridge etc. Far cheaper printers print much better than this. It's a disaster. It's going in the trash if they'll take it.
[EX A]:
negative
