Wireless IoT using NRF24L01+

Hi all.

Is here someone using NRF24L01+ wireless devices together with arduino (pro-mini or similar) attached with ethernet shield to control all of the IOT wirelessly?

I have developed my own ajax/websocket web server communicating with all such a wireless devices quite reliable in a reasonable range/speed.

Does anyone else has had a similar experience with such a configuration ?

It will be great discuss together what should be the biggest advantage / disadvantage of such a configuration.
