### ⭐⭐⭐⭐ Four Stars

Works as intended.

### ⭐⭐⭐ Pretty much exactly what you'd expect from a breadboard
*by C***D on December 2, 2015*

Pretty much exactly what you'd expect from a breadboard. Although some holes are bigger than others, sadly. Also some of the metal thingies in the holes could stick out, so don't force it in there or you might ruin that hole ( ͡° ͜ʖ ͡°)
