Work like a charm. Before it was impossible to use a sensor to check my mail, due to the unshielded din't reach my gatway.
But with this, no problem at all.
But the only thing, was that it was dilivered without the antenna.

I ordered the same module and it worked fine - though it uses an older chip (nRF24L01 without the '+'). It lacks error correction among some other features of the more commonly used newer version, which is backwards compatible.. and indeed, i only realised from specs it was the older version (i tested for a day or so - but during that time it seemed to work without issues).

I had problems with the range with some outdoor sensors. I didn't read the spec of this one, but read on a forum that this one was much better.
But when I tested it, it was a uge different in range compared to the other unshielded with antenna.
