Kester 24-6337-0027 Solder Roll, Core Size 66, 63/37 Alloy, 0.031 Diameter

Excellent! Exact product I was looking for and Amazon has it at the best price and eligible for shipping. Have purchased multiple times and will continue to purchase from Amazon.

good

Good 60/40 blend, but the rosin is pretty naty. Burns up little black chunks as you work and you can never tin an iron clean with it. Seems a bit caustic, have gone through a few tips I didnt expect to while using only 10% of it so far...

This solder smokes more than any other solder I have ever used in over 20 years, even for its size. Works well otherwise, wish I had bought a little thicker but that is my fault.

Great product. Better than normal 60/40. Flows better and melts more consistently.

Excellent!

Really good stuff

I love it.

This is the only brand of solder I use for my electronic builds and repairs. I like this formula of mix, seems to flow better than the typical 60/40. Also so do yourself a favor and don’t buy the cheap stuff from China, spend a little more and get quality.

Excellent solder. Melts and flows very easy.
