> 3 dayWorks great on all my small soldering projects around the house. Ive used it on circuit boards and on joining wires and it melts and flows perfectly. I chose the 63/37 solder because 63/37 solder is made of 63% tin and 37% lead. It has a melting point of 183°C, slightly lower than the more common 60/40 blend. Eutectic solders like the 63/37 are easier to work with as there is no semi-solid point when melting it, like there is with 60/40 solder. Its worth the slightly higher cost if you are working with delicate electronics. It works great with my

> 3 dayThis is really great solder! I was struggling to get some audio connectors to wet with cheap store brand solder, experimenting with all sorts of fluxes and tips trying to get it to work...as it turned out, all I really needed was some quality solder. The gauge is much smaller than I expected, probably could have saved a few bucks and gone with the .030, but it works great. You cant beat Kester.

Greater than one weekThis review is not of the Kester solder, but the seller, Kimco Distributors. I ordered a 1 lb roll of Kester 44, and when it came the spool was covered in sloppy packing tape, and the actual solder spool had a birds nest. I take that term from bass fishing - its meant to describe the mess you get when you use a baitcasting reel (which has a spinning spool) and dont stop the rotation before your lure hits the water. As I pulled solder off this spool, it was coming out from underneath many layers of solder which was deeper into the roll, but physically on top. So I kept getting kinks. I managed to cut a bunch of it away (had to throw away solder) and got down to the deeper part of the spool, where it was coiled tightly, but now still, the solder is coming out from inside of the spool. Its possible that this was screwed up at the Kester factory, but I doubt it. Is this seller re-spooling their solder, and doing a sloppy job at it? It makes me question whether Ive really got genuine Kester 44 at all, in fact.
