It's a good one, buy it.
Size: 16 AWG-100 ft
Actual 5 stars!
OFC, copper stranded wire, takes solder nicely when tinned, stiff and pliable enough to stay bent.
covering melts INTO wire as expected.
I was hoping for a good deal and got one.

Smaller than the original, but works well.
When I received it, it was so small that I thought it was a toy, or maybe for some 4cyl engine. It is significantly smaller than the original one. When I looked closer, the mount holes did line up, so I tried it. I did have to get shorter mount bolts.
To my surprise, it works great! I don't know what the longevity will be, but it made it through a busy august!
Considering the price and how small it is, I might just buy a second one to keep on board. Just in case.
