I’m really impressed with this liquid solder flux. The dropper bottle makes it super easy to apply just the right amount, and the consistency is perfect — not too thick, not too runny. It flows clean, helps the solder grab instantly, and leaves no mess behind. I’ve used a lot of flux over the years, and this one stands out for how clean it works and how reliable it is on small electronics. The bottle size is great for the price, and the quality is better than I expected. If you do any kind of electrical work, repairs, or hobby soldering, this is absolutely worth having on your bench. Bottle design is good and the applicator makes this a very versatile item to keep on hand with your soldering station or on the go. I’d definitely buy it again.

This liquid flux is perfect for my electronic repair and other projects. It is very effective in helping my solder flow efficiently, making solid connections. This flux doesn't leave a lot of residue which makes for easy cleanup. It may seem a little expensive but just a couple of drops is all it takes. If you do electronic repairs or build electronic projects, flux is a necessity. This is good flux and I recommend it. This has been compatible with my lead-free solder thus far.

I haven't used this much after the purchase as I mostly hand solder thru-hole components and wider pitch SMT parts. However, recently, I needed to solder some tighter pitched ICs and this flux saves the hand soldering. The solder wets on the pads and leads really well! Even for the drag soldering, the solder wick use was very little. Highly recommend.

Not bad, it's really runny and I've used better. The flow of my solder isn't great but it works

I’m not a big fan of using flux. Most times you can avoid using it, but there is the occasion where you need to use just a teeny tiny a bit of liquid solder flux, just to get things going. If you watch the YouTubes you may see several video creators that do retro computer restoration or what have you, just swathing that gunk all over the place by the half gallon at a time! Don’t believe it people! Melt a little new solder onto an old blob if it’s being stubborn, and you never have to use flux. Again, except for in certain circumstances. I do computer and video game console PCB repair, recaps, etc. I also work with solid state pinball machines by the plenty. There are times when components are just too close together or just stubborn going through a ground plane that you just gotta add a little flux. That’s why this teeny tiny bottle comes in handy. It’s got two types of applicator tip, one is molded into the model and the other is a screw on metal needle, which is super tight! Especially if you’re tighten it! My first use with this bottle was on a Bally pinball MPU board from the late 1970s. That suffered from battery leakage. Which means removing a whole bunch of components, cleaning the alkaline damage, repairing the alkaline damage, and then reinstalling new components that were damaged. This was actually the first time I used liquid solder flux on a board. Typically, I go without, as mentioned earlier, or use solder flux paste. This is much easier, and you don’t have to crank up the heat output on your solder iron nearly as much to get things free. My choice heat range is about 625°F, but with liquid flux, I could go slower, at about 550°F. These are my observations, your results may vary! Ask for value for money, it’s a little pricey for how little you get, but at the same time, I’m not going to be using this whole bottle in a day or in a week or maybe even a year, so the price isn’t too terribly bad in the long run. The quality is good, it’s not incredibly slimy like the flux paste, and much easier to clean off after being worked with. Yes, I would recommend this! It’s kind of the tool that you don’t use too often, but it sure is nice to have around!

Flux is flux. It is clean, and allows solder to flow when the proper amount of heat is applied. I recommend this product.

Much better than paste this works every time, not too thick or too thin but just right. Used it to weld solid copper wire 16 gauge the wire had laid around for a good bit but this Flux cleaned it up. Made for a good solid weld.

Easy to use, cheap, effective. Really helped the solder do what you need.

Really good stuff, cleans the metal well for soft soldering. East to fit parts. good value for money, not particularly sticky, but runs well into joints, Would recommend.

Huge fan of this flux, because it is easy to apply where you want it and very effective in improving flow and adhesion. I get really clean joints that flow so easily with this flux. It says it's "no clean," and I think that's a bit of a stretch, but it does clean up pretty easily, especially compared to other fluxes I've used. Also, it lasts a long time. I've used it on every joint (and there have been a lot of joints) for a couple of months now, and I'm maybe 1/6 of the way through the bottle. Plus, it's a Guatemalan company, which I appreciate. It's nice to actually have global goods in a global market, and not just all the goods coming from the same city in the same country (no shade, Shenzhen).

Excellent product for clean soldering, worth the cost

Probablemente un buen producto pero llegó en mal estado, la tapa no estaba bien cerrada y había una fuga en el embalaje. Espero novelas…
