You have to use the standard caution because you are working with a certain amount of radio frequency i.e. short wires, bypass capacitors, good power supply. The result is a fantastic toy to make data transmission over a long distance.

After I received them (3 modules), they did not work at all. I found from many web that they should put a capacitor ( VCC(3V) to GND) to filter power source. After some modification, They worked well.
