Amazing product
This product is a lifesaver for small soldering. It melts fast and sets shinny. I have uses Kester's with the silver in it and this product flows much better.

Great Solder Wire To Replace Capacitors in DVD/VCR Player
Used this Kester 44 Solder Wire to repair 5 blown Capacitors in my 2008 Panasonic DVD/VCR Player/Recorder. There’s a lot of solder wire in the tube, more than I’ll ever need for repairs on my video equipment. Did the job nicely. Very pleased with the results and my VCR/DVD recorder is back up and running again!

Highly Recommended
Wish I’d have found this solder years ago. Always struggled with joining wires or terminals. This stuff melts and works so easy. If you’re an amateur like me doing some shade tree work now and again, it’s well worth the investment.

Very easy to work with
Flows at a low temp, nice and smooth makes your repairs much easier using , picture is deceiving more solder in the tube than expected

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

Flows well and great for fine work.
This solder was recommended to me by several high end electronic DIY’s and EE’s and has yet to disappoint. I have used other brands which were quite good, but this remains tops on my list. Great for fine work on circuits.
