3 Pieces No Clean Soldering Pen Rosin Solder Pen for Electronics Tabbing Wiring Solder, Welding Maintenance of PCB Board, Liquid Solder Pen

I really like these pens they’re super easy to handle. They dispense less flux than the syringe, but it also means less cleanup. I wouldn’t use this for anything that’s going to require a ton of flux because it probably won’t be as practical but for small components and small wires. It does amazing.

My Kester pen flux ran out (really oozed out all over my soldering box) so I bought this one to see if it would work as the price was right. The flux works great and thus far the pen design has kept the flux where it belongs, in the pen.

These Flux pens are just ok. They are good for precise application of flux, but the flux itself doesn't work that great.

The best way I've found to use these is shake them a bit while still inside the cap, rather than pressing them to dispense the flux. It works really well on wires and even PCBs, and conserves flux so well that I haven't run out of one of these in months of nearly daily use.

It's nice to get 3 sticks of flux pens. But the applicator doesn't let out enough flux to be really useful. It's good if you're doing really small soldering on a mother board or something. But for larger solder projects these flux pens are pretty useless. Even using these just on my 1/7 scale rc car it didn't help me solder and I used the old flux I had left over. Overall, for very small wire soldering this could help but for most solder projects I'd get a flux paste, not a pen.

I use this every time i solder anything and it helps a lot with soldering my drones and have three is great for when i run out of one i still am using the first one i took out the package and its still got a lot left in it.

It's good for quick swabs to the circuit board. However you'd have to keep applying, since it evaporates too fast lol

I finally got a product that works for me thanks guys
