Perfect wire for marine use. Only wish I should have bought double the length for my project installing multiple graphs in my boat.Definitely worth the price and shipping was fast. Will be buying more in the future.

Excellent quality, I highly recommend this manufacturer/seller. I’m using it on a build out for my over landing rig and I would recommend it to anybody that is in need of this gauge or any gauge from them. I will be buying from them again.

This ended up being a little less flexible than I expected, but it still seems like good quality wire and I was able to make it work for what I need. I don’t think I would suggest using this in a situation where it’s constantly bending and flexing. Some is fine, but not in a motion system.

Nice wire, flexible insulation and nicely tinned wire. Folks for marine use you want the tinned copper conductors, bare copper oxidizes under the insulation due to humidity making it a real pain to redo connections if necessary because cleaning the oxidization of the wires is diffuclt without using acid flux.
