Great product! This is perfect for soldering stranded wire and making small solder joints. The liquid flux flows into the strands of the wire and allows the solder to flow into the wire very quickly, forming a good strong joint with just a very small amount of solder. The applicator tip is the prefect diameter and length for applying the flux precisely where you need it. Despite the small size of the bottle, it should last a long time since you don’t need to use much at all.

I had previously purchased from Amazon, a Weller flux bottle setup with MG flux. The similar size Weller applicator bottle also had a needle top to replace the larger plastic applicator, like this one.There was no way to use the needle applicator. Flux was too thick, it leaked out past the threaded base when you slightly squeezed the bottle to try and force the flux out of the bottle thru the needle. Mess, un usable unless you used the plastic insert, even that leaked and was a bit of a mess , just not as bad as the needle cap.This, one , perfect, no leaks, flux is thin enough to drop out w/o pressure on the bottle. no mess no fuss.Winner !

Works very well. Solder flows nicely and is very easy to clean up. Just need to remove the cap and the clear spout and replace with the needle spout/cap. Sealed very well in bag, I saw no evidence of leakage in the packaging.

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.)

Works great! Nice packaging and easy to use, helped me resolder some of my Harley electrical connectors. This is a quality item, but if I had to do it over again I'd get the paste as it's easier to work with.

I use it whenever soldering. One drop of it makes good round soldering. Love this product very 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

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+
