This flux works fantastic!! Most negative reviews appear to be made by folks who don’t really understand working with flux. Good flux is typically VERY sticky… almost like tree sap. It cleans off easily with acetone (nail polish remover, carb cleaner, or brake cleaner all work great)The cap/tip that comes with the bottle works VERY good and makes the flux application much easier onto small wires, BUT, it’s a little hard to figure out. You HAVE to remove the small plastic tip that’s installed BEFORE you can screw on the metal tip. If you simply push the plastic tip to the side, it should pop out. Then you can screw on the metal tip. Would be helpful if they included some instructions to explain this… took me a while to figure it out at first. But once that’s installed, you’ll find that this stuff works really well.It is also a LOT of flux compared to those annoying flux pens that tend to either go dry OR dump a crapload of flux on your wires…. almost never the exact amount you need :) This bottle however, makes it super easy to get the exact amount you need, every time.If the metal tip gets clogged (which will likely happen at some point) heat the tip up a bit with a small heat gun or lighter and it should free up easily.

Works perfectly, easy to use and apply.

This works well! A little goes a long way. It does keep the soldering job clean. You have to remove the original plastic spout in order to fit the included needle spout. Replace the plastic spout when done with the soldering job so the cap seals tight. I think its a good value, performance vs cost. A+

This liquid solder flux dropper is the precision tool I never knew I needed—until I used it and realized I also need a steady hand and the patience of a monk. The flux itself works great, but one wrong squeeze and you’ve got a tiny chemical Slip ‘n Slide on your workbench.The dropper tip is so fine, it made me feel like a surgeon performing open-heart soldering. Spoiler: I am not a surgeon. Things got messy, but hey, the connections were solid, and my ego only slightly bruised.Rating: 4/5 🌟 (Works great, but beware: one extra drop and you’re in flux overload.)

Easy to use and does the job. The liquid is very thin so don't use too much otherwise it runs all over your circuit board. The fine needle dispenser is useful for controlling the liquid flow.

works well.

Does the job well, but be CAREFUL to not get this ON YOUR SKIN!There should be warnings that it is very irritating to skin.Mine came leaking in the package and got on my hands.Immediately my skin burned and also became very itchy!Otherwise, works very well

Great value. This product is excellent when soldering. The solder melts & flows well. The viscosity is not too thin & not too thick. It permeates stranded wire easily but stays in place where you put it. It can leave a sticky residue around your solder joint but I have found it to not be a problem.
