The packaging was real nice and it included the specs.
One of the mounting bracket for the switch is a bit bent and rusted, thats okay though because I'm not going to use them, and even if i was i would just sand them down then polish them up.
I got one plugged in and it looks nice, it was a bit of a pain because all the wires, but to be honest I need a better case and PSU in order to get them how I want.
Everything works fine, I'm a bit dissapointed by the red LED's though as they arent bright at all and barely lights anything up, but the green and blue are fine.
Compared to my old 120mm(http://www.newegg.com/Product/Product.aspx?Item=N82E16811998124) the b-flexi is just as loud and gets less airflow, however the fact that I can change my LED's color makes up for that.
If i where to rate them I'd give them a 3 out of 5. They're nice, but if you can put up with the same lighting day after day after day then get something else.
