## Description

DOM 2018

Review: Works well - I have a few hobbies that occasionally need to do soldering for. This works well and I was happy with the performance. I think it worked better than the cheap stuff I had before. This thickness was also easier to work with for a circuit board I soldered components to.
Review: Thing’s just not what it use to be - Buying this for the exact chemical composition was a mistake. Sure I need to replace an old stocked product which I’d used entirely. Additionally the old Kester was perfect. There’s so much resin in this that it’s caused some of my batteries to overheat. For $20 at Harbor Freight you’ll be just as satisfied; if not more.

## Features

- This solder has virtually dominated the field of activated rosin core solders for well over four decades
- An outstanding performance feature of this flux is the “instant-action” wetting behavior
- The high mobility and fast-spreading action of this flux results in more reliable production line soldering
- Classified as ROM1 per J-STD-004
- 1 LB Spool

## Questions & Answers

**Q: What is the different between this and the white spool solder with the same part number that is sold by the same sellers for a few dollars more?**
A: There isn't any difference between the white spool or the black spool.  At one time, Kester had been using both black and white spools for their solder products. This image is a representative image.

### ⭐⭐ Thing’s just not what it use to be

### ⭐⭐⭐⭐⭐ Its worth a little extra $ for the better stuff (like this Kester 44)
*by A***R on January 29, 2021*

I'm retired now but I was the 'go to' guy for SMD and all other sorts of soldering at several major companies. I tried the 'west of the pacific' solder and they were just not worth bothering with. I did have some successes. But I also had some abject failures. Now I think for something I do so rarely now I'll just stick with Kester since I have faith and experience with them and I just don't want to mess up some more expensive stuff with saving a buck.
