Review: Good quality marine wire - Good wire at a great price
Review: Good Quality Wire, Flexible with Distance Markers - 16awg - good wire in a very nice casing / sheath. Flexible, yet strong. Feet markers also printed on the casing makes it even more useful (although there's a lot of stuff printed on the casing, the feet markers could have been larger to make them easier to find). Overall -- I'm very pleased with the quality of this wire and would highly recommend. Good job Gearit.
