A perfect wifi antenna at any point

I was looking for a way to better capture my wifi network in a room located at over 10m with a box through the walls.
I am not disappointed with my purchase.
Before my wifi network at times fell below 5Mbts / s, described as mediocre by Windows. Now I always captures my wifi network, with an oscillating flow between 54 Mbts / s (in the worst time) and 150 Mbts / s, the maximum that can issue my box ... what could be better than perfection itself .
Also thanks to its base (weighted by weight), the antenna is very stable, and lands anywhere.
It can even be hung on the wall (not supplied screws).
As against the 1.20m cable is a bit short, but not of great relevance when this antenna can be placed anywhere on your desktop.
My personal rating: 10/10.
