Pros:

• small and simple, doesn't require much space
• finds best wifi spot in your home
• you can check different stats from home, who's home, the arrival time, who's using the internet etc.

Cons:

• it's controlled via smartphone, if someone can acces your phone he can acces your fingbox

On a short notice, I like fingbox, it's usefull, I rate it 4 stars out of 5.

(All of the above is just my opinion about this product)
