Query: Not worth the time and effort

I did buy this for a good deal, but getting this thing to work was a nightmare. Almost no helpful documentation is included - make sure you already have an internet connection available so you can find help on how to get this working.After spending a lot of time and frustration trying to make it work, it barely extended any signal. I was very hopeful this would solve some connection issues I was having but this caused more trouble than it was worth.
