Purchased this product after moving to a different room where my internal wi-fi adapter had very weak connection and no connection at sometimes. And after using this, I have a great connection with upto 60% improvement and no disconnects. Just had one little problem at the beginning which I blame for the lack of good instruction on the manual.
After installing the drivers, when I tried to connect it to the internet which it was showing fine, it kept saying straight away that the could not connect. I looked all over for help but to no avail. Then I noticed there was something called QSS driver and finally I noticed it in another manual which I downloaded off their site which says to press on the QSS button by the side. Very small button with no indication it is there. After pressing it and putting the password, I had the internet. It was that easy even with the livebox router of orange.
One thing the manufacturers could improve could be the light signals that flashes to notify the user which sadly right now confuses rather then helps.
All in all, money well spent on a good piece of equipment.
