This product is a complete waste of money... As a result of using this product, I found that it was not able to handle the industrial and scientific demands of my electrical setup. The insulation on the connectors were woefully inadequate and continuously resulted in shorts in my wiring. The only positive thing i can say about this product is that it was cheap, but that's hardly an advantage when it doesn't work. Save yourself some time and money, and invest in a more reliable option..
