Ok guys, lets talk ECU's

So yesterday I called Oreilles for an ecu and they said they had one and it was $28.99. I found it on their web page and it was a chrome looking box but said made in China, figured ok I'll try it.
My wife had to go by there and said she would pick it up for me, I said ok lol
She brings this thing home and it's blue not chrome and says made in Taiwan, ok well whatever.
Now the weird thing happens, I shook it, I don't know why but I shook it and heard something. I put it next to my ear and shook it again, sounds like a maraca.
WTF?!?!? This thing sounds like there is sand in it...............back it goes tomorrow.246508876_1267746513652780_5637047151020510054_n.jpg 246815402_1267746556986109_320915703056763523_n.jpg 246815402_1267746556986109_320915703056763523_n.jpg
