You are welcome to add more examples of faked chips. We will add that information here.<br/>
Some users reported better connection or longer range through more walls when using the
"E01-ML01DP5" EBYTE 2,4 GHz Wireless Modul nRF24L01 + PA + LNA RF Modul, SMA-K Antenna connector,
which has an eye-catching HF cover. But beware: It comes without the antenna!
In any case you should stabilize the Vcc power by a capacitor and don't exceed the Amplifier Power Level "LOW".
Users reporting good connection over 10m through walls / ceilings with Amplifier Power Level "MIN".
It is not always the bigger the better...
Power levels "HIGH" and "MAX" are meant to wirings where the nRF24 is supplied by an extra 3.3 Volt regulator.
The bultin regulator on ESP boards has only low reserves in case WiFi and nRF are sending simultaneously.
If you operate additional interfaces like a display, the reserve is again reduced.
