Why people recommend it
A DroneBot Workshop tutorial pointed to as a good introduction to connecting cheap 433 MHz radio modules to an Arduino.
Watch for: Module pairs differ, and cheap ones can be unreliable
In their words
The most commonly used 433 MHz module pair demonstrated on the Internet actually seems to be the pair with the markings, FS1000A and MX-RM-5V 080408 (e.g. Using Inexpensive 433 MHz RF Modules with Arduino).
