The flux works great. I've used it to desolder some switches and resolder new ones on and also used while replacing some tiny resistors on a Dreamcast board. Flux is a must and I like this paste with the needle applicator. Helps you put the flux where it's needed.I also appreciate the reusability here without making a mess.At 7 bucks this is an excellent purchase. If you need to solder something get this flux.

I have a lot of DIY electrical projects. Most involve my Jeep; not only is it my toy but it's a platform many other toys. I have LED pods, lighting strips, whip lights, a big audio system. I don't often use solder as most of my connections are inside a vehicle, and it's not easy to solder in a vehicle. However, sometimes I can do some of the connections at a bench, and sometimes solder is the best option. I was running low on flux so when I saw this listing I had to try it.It works! I've tested this on a few soldering connections and the solder bonded nicely with the surface. Flux is needed if you want long-lasting solder connections, and I prefer to build things to last.Overall I'm happy with this flux paste, and when I run out I'll certainly consider this brand again.

I'm not sure how to judge flux quality, but it work like any other flux I've used. It wicks into the tiny crevasses & pulls in the heated solder. So, that is great. I used to use a toothpick or tiny brush, but really liking the needle applicator. Keeps things much cleaner. This is good for me!

I got this to replace the flux I was previously using which I was beginning to run out of, and so far this has been just as good. It heats up and melts good and at the right temperature, and the rework I've done with it has been nice and easy with this used as normal. I have no complaints, four tubes should last me a bit, and it's nice they provided the luer tips for easier dispensing.

I have done quite a bit of soldering as a hobbyist maker. I am no pro! I have laid some solder that I was truly proud to have visible. I have also created my share of ugliness. So, that's my skill level. I have been using vat of flux since I first started. In general, it worked alright. I always struggled with getting the flux onto the components. If my wire is too hot, nothing comes with it, almost nothing. Or I end up with a huge blob when my wire is colder.I love that this comes in a syringe. I think I know so much, I mean, I write reviews. Yet I had no idea of how nice life could be. I LOVE the fine control the needle affords. I can put exactly the amount of flux exactly where I want it. That thrills me. I'll admit I'm getting older and my hand is a bit more shaky than it used to be. That does make placing the needle while I'm squeezing it a little hard. I think once I know how hard to push to not get a stream across my monitor, I should develop somewhat more dexterous hands.As others have reported, this flux really spreads nicely once it gets heated. I like watching it wick through the wires. It is quite beautiful, the way it glistens and deepens the natural luster of the copper.Anyhow, good stuff. I'm a total fan! Thank you!

I do circuit board repair work and frequently have to replace SMDs (Surface Mount Devices). I have found that it is almost impossible to re-solder anything back in without using this soldering flux paste. The amount in the tube seems small to what we used to use when doing discrete component soldering but the SMD parts only require a small touch of it to get the job done.It comes in a seal package to keep it fresh. Applying it is done with a syringe tip needle that screws onto the syringe body. Make sure you seal things back up after using it to preserve the flux from airing out. It usually has a 2 year shelf life but if you seal it up good after each use I find it can last a lot longer.I highly recommend it if you have never used it yet. You will be surprised how easy it makes a job that was impossible because the solder wouldn’t flow or stick and ran all over places you didn’t want it to.

This flux is pretty decent, there is minimal splattering and decent adhesion. The syringe that it's in work very well and helps a lot with getting it exactly where you need it. I used this while soldering a bunch of XLR jacks in a recent project. The solder flowed pretty well but I do feel like it burned up a little premature.
