Good Wire. Will definitely consider for the future.
Size: 2 Colors each 5FT, Style: 10AWG
Nice wire. Comes inside a plastic bag. Wire is soft and flexible. Worked as exactly needed for my boat wiring. It was easy to cut and crimp connectors on. It has a thick layer of insulation around the wire which keeps it from getting damaged.

What a lifesaver!
Model: 17749N, Model: 17749N
The usual box stores wanted around $150-$200 for a New and or Refurbished starter. The Ezexpreze 17749 was such a great deal and It bolted up nicely to my 1999 TJ with the 4.0 4x4! Its a great replacement, I've had it for about half a year but it starts with ease. I'll definitely get me another one as a backup at this price point!
