Nice improvement
Compared to the stock antenna, this one definitely extends my range. It's a bit longer, but that's expected. The build quality feels good. I'd recommend it to anyone looking for better performance.

A bit flimsy
The antenna works, but it feels a bit cheap compared to the original. The range improvement is modest. I've had better. But it was cheap, so no major complaints.
