Maybe it's adding a bit more signal hard to quantify. But in instructions it's like you put instead of your phone antenna...

The state is good. at how much the signal will be accurate will not check yet. and so everything is super. I recommend it.

Good Goods and the seller also did a great job and the packaging is also well done, in fact I have not checked yet

Got what she will give, I'll check when I put it in a cell. I think it will catch the reception even better.

Received quickly delivery is excellent, but I did not feel improvements, I advise the seller to everyone ..
