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

Makes much better joints and much easier to use than R/S Chinese version. I highly recommend this over other solders.

Perfect Solder and its lead based, so use a fume exhaust. I was reccomended this buy Louis Rossman on Youtube. Great Product.

Its the solder Ive been using for over 50 years.

OMG! I should have gone with this before! This has literally changed how I solder. It made it fun and quicker to do some of my diy projects! I will not use another brand again! no more bad solder joints

Great solder. Much better than the old crap they used to sell at the Shack.

Works great!! Using it for FPV circuit boards. Works amazingly!

Kester eutectic leaded solder is the best on the market. Never have any issue with the flux or the ability to install SMD parts. Highly recommended.

This is the best solder on the market! I will never use that Radio Shack garbage again for anything but maybe wire or something.

Its exactly as expected. High quality solder.

This is really good for small soldering connections.
