                How can you rate the wire when you purchase it. I had no problem finding the correct wire in the electrical department. The only comment is this wire is very expensive to buy so I will only give it a four star.

                Easy to cut and wire into existing wires. Love the thickness of the wires not very easy to bend. I really needed a 12/2. Not a 12/3 however this is what the salesman recommended to wire up a outside ceiling patio fan with remote. Made it work i just had to tie off the 1 extra wire. Overall great product.
