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.

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.

Lasts forever , easy to use , no mess, no flux, perfect 100/100%
This solder is perfect ! It works instantly without any flux ! Amazing heat transfer easy to clean…. The size is perfect for the cost ! I highly recommend this product over any solder if you’re using it like I am on wiring. :) will buy again but it lasts for ever

Great for precision applications or repairs in the field
I use this for working on drones. Specifically for tiny whoops and small builds. The slimmer solder wire is much easier for precise joints, melts and flows well, and overall is one of my favorite solders I've tried to date. Also great for travel if you're into FPV drones and need to do field repairs. Would buy again!

Flows nice!
Just buy some! Best solder I’ve ever worked with. Flow esay and didn’t need ton of heat. It works well on most all of my RC and FPV needs.

Don't take any wire out. Be careful.
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

Get quality solder in small packages
I love the fact that I can buy quality Kester solder in less than full one pound rolls. Awesome convenience.
