Kester 24-6040-0053 Solder Roll, 66 Core Size, 0.050 Diameter

It is worth it. Don’t skimp on cheap stuff. It makes electronics work so much easier when you have good materials.

The product itself is fine if you dont need recent production. If youre buying it chances are you know what youre buying and dont need a review for that. I bought 2 different rolls from this seller (different diameters). The first one the cardboard box was a bit beat up. On both the place where the date of manufacture usually is was peeled off. They put clear packaging tape over the top of the entire thing which makes it less noticeable. If you didnt know there was supposed to be a date of manufacture there you would probably never know the difference. According to Kesters own website the shelf life for flux cored solders is 2 or 3 years (depending on formulation) which is why they put a date of manufacture on them. For what I do it really doesnt matter. But if youre buying them for an application where that is important you dont want to buy from Amazon/this seller. In the future Ill just spend more $$$ and go with Digi-Key so I know what Im getting hasnt been laying around for a decade. It seems disingenuous to sell something as new which has a shelf life and then to remove the information from the package which states when it was made.

Not much to report here - I have used Kester 44 solder for 60 years. Number 44 is an old formula that contains lead, so if you are doing work that requires lead-free, choose a different product. The rosin flux cleans easily with solvent. If you need no-clean, choose a different product. Number 44 remains my favorite because it is easy to work with, makes reliable joints and is easy to clean.
