    • Nice solder
Size: 1
Very nice solder to work with, melts and flows well

    • Buy on Amazon - not ebay due due to shrink
Size: 1
Buy sealed on Amazon not eBay where unscruplious sellers will take off a few rounds to pocket and still sell the rest of the roll as new. Excellent solder, using for nearly a decade. I love it has lead (despite industry downplaying that as content.

    • The best solder you can buy
Size: 1
I was recently running out of the 60/40 solder I had bought a few years ago for my guitar projects. I happened upon an old package of Kester leaded solder that my dad used many years ago for his occasional soldering projects. It flowed very well, solidified reliably, and the solder joints were consistently good. I eventually ran through my dad's Kester solder and had to shop for another solder. I was surprised to find this Kester solder, and I ordered it right away. Note that I prefer this 0.05" diameter, as it's the same gauge as my father's old solder, and it's the standard size I'm used to. It's helps me to flow more solder when I need it. This Kester solder flows just like the older solder, heating up very quickly and consistently. The difference I notice is that the solder takes a moment longer to solidify. I need to wait a little longer before making sure the joint is firming up. Not a criticism, just an observation. I expect to be using Kester solder for many years to come. ... show more

    • The best on the market
Size: 1
This is the only solder I ever use. I have had great luck with it and would highly recommend it to anyone. The flux action of this solder makes it flow very well, leading to clean joints and quicker work. The .05 size is perfect for most projects, but I recommend a lighter gauge like .031 for working with small PCBs and smaller wires. The solder comes with a date of manufacture on the reel, so you will know when it is time to replace it if you have not used it up. IMPORTANT NOTE: Storage and Shelf Life Storage must be in a dry, non-corrosive environment. The surface may lose its shine and appear a dull shade of gray. This is a surface phenomena and is not detrimental to product functionality. Flux cored solder wire has a limited shelf life determined by the alloy used in the wire. For alloys containing more than 70% lead, the shelf life is 2 years from the date of manufacture. Other alloys have a shelf life of 3 years from the date of manufacture. ... show more

This solder is the go-to item for small parts. Works fine though I am always surprised how expensive it is.

    • It's Kesters. What more is there to say? As good as it gets
Size: 1
Kesters has been around for over a hundred years and this is why, very high quality products. Yes there are cheaper brands out there but Kesters gives consistent quality spool after spool after spool.
