Involvement:General (knows how to use it) - Ownership:1 day to 1 week

Pros:
Very nice clear display. Nice blue backlight, and relatively easy to get going with some tips. Ideal for my small project and seems like it is solidly built.
Cons:
No instructions, so novices would need some help to get going - not quite a plug and play, but fairly close.
Other:
Using some google-fu, I tracked down the library and connections that made it work: the u8GLIB library http://code.google.com/p/u8glib/wiki/thelloworld a very handy post http://parenthetic.blogspot.co.uk/2011/12/hello-world-in-arduino-with-st7920-lcd.html and the datasheet http://www.dfrobot.com/image/data/FIT0021/ST7920.pdf I ended up with the following wiring: E = ESCLK = SCK = PB5 = D13 R/W = RW = MOSI = PB3 = D11 RST = PB0 = D8 RS = a0 = d1 = Data/Register select = D9 (in the picture I also linked PSB to GND (to select serial input). Don't know if this is required. and wiring BLA = A = 1.2k resistor to 5v BLK = K = GND VCC = Vcc = 5v GND = GND I then uploaded the 'Hello World' example from the u8glib, and uncommented and changed the header line from the defaults: U8GLIB_ST7920_128X64 u8g(13, 11, 9, U8G_PIN_NONE); // SPI Com: SCK = en = 18, MOSI = rw = 16, CS = di = 17 This got me showing the 'Hello World' on the display.
Bottomline:
Excellent value display - would buy more.
