Great price for really decent wire
Great stuff. Welds well with little splatter. Competes with the big names especially at the price point. I've gone through 4 rolls now and and it's very consistent in quality. I enjoyed the sticker that came with it too.

How was this 2 lbs?
It seemed like I went through this wire very quickly. Then I looked at the actual spool, and compared it with a different 2 lb spool I had on the shelf. Am I loosing my mind, or is it virtually impossible to put 2 lbs of wire on a spool with a core this thick?

Old stock
It seems old sticky wire, lots of spatter. much worse than Harbor freight wires.

Wire has rust all over
My wire arrived covered in rust… the pictures show how bad it is.. this wire was recommended to me after I found rust on 2 different spools of Lincoln wire I recently bought, good thing I decided to try a small roll first! I just need some wire I can actually weld with that’s NOT covered in rust! 🤦🏻♂️
