Perfect thin Solder
Item is perfect. not a lot of cleaning needed, but a little cleanup needed for the Flux Rosin core. other than that it is easy and a breeze to use. Makes for easy fixing of those smaller components that take less time to heat up. Perfect for the price!

Worked perfectly, to solder a fan back on the motherboard in a Mac Mini
This was a bit of a life-saver. I had taken my Mac Mini apart to discover what my upgrade options were (a disappointing experience, to be sure), and my disappointment was punctuated when I realized I had inadvertently removed the housing for the fan connection from the motherboard. I don't know if it was ever properly soldered in the first place, but I knew that without the ability to cool, it would not function properly. I have very little soldering experience, but after watching some videos, and using this solder, I was able to get it working again. The connector had 4 pins, and I knew I needed something super thin, to avoid spilling over to the neighboring pins. And gratefully, by the grace of God, I was able to get it working. Happy with this purchase.

"It's so tiny..."
Mind-bogglingly thin. Like soldering with mythical elven gossamer. A delight to use when precision is required.

the ability to solder
Just what I needed.

Great for SMD work
Because it is so thin, this solder works very well with SMD components, which are very small and require less heat than thru-hole components. Together with a conical tip soldering pen and a lighted hands-free magnifying glass, SMD work becomes much easier.

Good for keyboard builds
It’s super thin which is nice. Melting point is higher than advertised. That it’s it’s my soldering iron. Good for keyboard builds.
