## Description

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

Review: Great solder wire - This is great solder wire. Melts fast and works as expected. Well worth the price to buy a solder wire that simplifies the process.
Review: Great solder, the only brand I'm using in the future - 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.
