PROS
Good brightness at even lower than 1ma! that's very low power consumption. Standard pin spacing, goes very easily to breadboard/pcb
CONS
Poor packing (no foam to protect pins) luckily, no pins were bent. no datasheet/other electrical information on site.
Okay, so this is biggest 7 segmenbt i'we seen, but sure, you can build as big as you like from matrises....but that's another story.

Where this could be used well, is house numbering, or any other outdoor applications, didn't test how far you could see it, but most likely would make door number or some other display when good visibility is needed, like in fog/darkness. test it out! but, for that, you'll need some basic electrical information about this product (don't want to burn this baby do we now? so here come some:

pinout, pin numbers are next to pins:
Anode:1,8 (plus/vcc)
A:7
B:6
C:4
D:3
E:2
F:9
G:10
DP (Dot):5

next, the forward current, maxinum is probadly 20ma. At 12v for segments a-git's around 15ma, and that is bright enought for most purposes. For Dot, at around 2.5v, 15ma

segments a-g 12v/15ma
dot 2.5/15ma

Now then, i can't press the importance of current limiting circuitry when playing with leds, they'll burn easily, and you CAN'T replace these leds inside segments. So, test carefully with current measuring, dont trust these info, factory sometimes does funny things, miswiring and such.
I don't take ANY responcibility if you put 12v to DP and burn it.

Enought of sounding like an, well you know. ENJOY,don't be too afraid of those perhaps too harsh words...!
