KEYESTUDIO offers the highest quality products, especially for Arduino. The TNRF24l01 module's 2.4GHz wireless transceiver works as advertised. I use them for educational purposes and for the wIfI Joystick & Robotic Car project. I can get the two to communicate back and forth but I have a few bugs that need fixing in the motor controls, most likely a programming issue. PS Connect the module to a 3.3V power supply, or preferably use the nRF24L01 adapter module available from Revain.
