Kester 44 Solder Wire, 63/37 0.031”, RMA Rosin, 1-ounce Tube

The GOAT. Awesome solder and this is thr only solder I use with my Pinecil V2 Smart Iron. This stuff makes soldering much easier and if your wire is pre-tinned its even easier to get it to soak into strands vs un-coated. Been using this on all my RC cars motors & escs. Works great making longer charger leads and battery adapters. Perfect smooth & shinny silver welds. I use this with Rosin Paste and it sticks very good.

Works perfect 👌

THIS is the solder ive been looking for!! About out of my 20yr old unbranded roll thats the best stuff ive ever used and been buying different ones to try and replace it but they are all trash that doesnt melt(its not the lead free bs) or flow good and SMOKES like crazy. This kester is spot on to my old stuff and now i wonder it i had a roll of kester all along. This melts and flows amazing with very little smoke at all and no bad/unusual smell.

Great quality.

Only use this product if you are soldering on something that matters. Any other solder on in replacement of this solder on a critical component is sure to deliver total failure. High quality solder is irreplaceable.

For years, I thought I was just terrible at soldering. I assumed the Maiyum solder I bought was good quality — turns out I was very wrong. I’ve left countless cold joints in my guitar cavities over the years and have absolutely burned up multiple pots trying to force a clean, shiny connection. Then one day it hit me: maybe the problem wasn’t my technique… maybe it was the solder. So I picked up this solder, and the difference was immediate. Suddenly my joints looked clean, shiny smooth, and genuinely professional. It made soldering way less frustrating. Absolutely worth the money in my opinion.

I'm sure it is good solder but you have to be careful. There is a small hole in one end cap to pull wire through so it looks like the picture. If you use the other end, the product is wrapped in there like a slinky so once you take it out, you can't get it back in the tube. I thought the packaging would be better

I've been using inexpensive solder for most of my life, I had gotten used to how horrible some are to melt and work with. While I'm not an expert at all when it comes to soldering. I've done enough to know now that I've been using junk in comparison LOL. For a new project I'm working on that requires soldering headers onto a fairly expensive GPS unit, I decided to do some solder research and came across this company. Yeah, it's more expensive than the others. But it's made here in the USA and I'm pretty sure most professional folks are using this because of the quality. Do your own research. This stuff is awesome. It melts quickly and easily and flows nicely. I'm never going back.
