Very good value for money. Easy to program via a serial interface and the Arduino IDE. Can even handle a simple web server. Has two General Purpose IO pins where you can read sensors or control things (Note that the whole thing runs on 3,3 Volts!). I use these modules for example to be able to check via the internet whether I have locked a door (with a magnetic sensor). Such a system costs less than a tenner (and that's incl. 3,7 Volt 1800 mAh Li-Ion battery).
