Very nice product and very cheap ! You can achieve fast (2Mbps) communication between two(2) Arduino (or Raspberry Pi). Attention 1: As with any transceiver, you need to buy two (2) to do the job. You may also need two Arduinos in order to experiment with this product. Attention 2: This product does not work together with the Arduino's motor shield because SPI library used by nRF24L01 shares the same pins on the board. Attention 3: You may also need to buy cables in order to connect each transceiver to Arduino. You need 7 cables for each piece. Note 1: There are also some variations of this product with a much better antenna, to achieve a longer communication distance. Note 2: The printed labels on the board are not easy to read.

Works fine! Module is very compact and lightweight. If you have problems running it: make sure you have a clean 3.3V power supply connected to it, you might need a capacitor of 100 or 200 uF between 3.3V and GND-Connection. Also check out if you are using the right pins (SPI). Some Arduino-Libraries are a bit confusing about CE and CSN Pins, so make sure they are connected as defined. Level Shifter is not needed, Input is 5V-tolerant, only operating voltage should be kept at 3.3V
