This flux worked great, needed to solder some lugs onto some 0 gauge ofc power cable for audio system and this flux worked great to help the solder bond, applicator is nice, no more worrying about finding a clean brush, bottle is leak proof

This rosin is very thin and flows nicely allowing you to flood your work area. I run my iron hot (600c) and it doesn't burn up or leave any residue that can't be easily cleaned up with IPA. I like the vial better than syringes, in my opinion it's easier to manage and you get more rosin for your money. What I like about this flux is that it cleans up really nice. The attached photo is a PCB after I soldered some programming headers, de-soldered them, and cleaned up the pads with IPA. There's no trace of the rosin flux.

In terms of soldering, this stuff did its job, the issue I had was my fault due to my own inexperience. If you're a newbie to soldering like I was and are trying to Solder something like Controller Thumbsticks, this stuff is going to get really sticky and sappy. What you want is the "clear no-clean flux" type for controllers and stuff. It cleans better. This stuff is basically like setting syrupy sap on fire on your circuit board, and the more isopropyl you use to clean it off, the more it gets everywhere, never really getting clean. Also, if you're dealing with Thumbsticks/buttons like I was, keep in mind that the stuff is sticky and hardens when cooled off, meaning that the isopropyl has a chance of washing/guiding the flux you're cleaning off INTO the button/thumbstick, HARDENING, rendering your button inoperable. This is fine, you just need to keep flushing out the button with isopropyl and compressed air until you finally flush that sticky flux out preventing the button from working. I noticed my L3/R3 buttons stopped working after a Thumbstick replacement job, just had to keep putting isopropyl drops and blowing out with compressed air can until it finally got flux out. Flux is a necessary evil, you absolutely HAVE to use it when soldering/desoldering, this stuff is just a lot harder to clean than the clear no-clean type flux. Do some research, so if your job actually needs this type, because I wouldn't use it personally if I didn't have to. It works well, the cleaning is just a lot harder.

They definitely mean **liquid** when they say “liquid flux.” That’s on me—I was hoping for something with a consistency somewhere between paste and liquid, but their description is accurate. As a flux, it does exactly what it’s supposed to do and helps the solder flow nicely. Because it’s a true liquid, it also flows *everywhere*. This can be helpful, but sometimes problematic. When soldering through-hole components, for example, it drips straight through and coats the underside of the component, which isn’t always ideal. For those situations, I’m finding I still prefer traditional paste flux. Cleanup is typical, maybe a bit stickier than what I’m used to. You’ll definitely want IPA on hand to clean it properly. One small note: The package didn't come with instructions on how to install the finer-point nozzle. However, if you scroll through the product photos on Amazon, you can see how it’s done. Once I figured that out, installation was easy and the fine tip works really well for getting flux into tight areas. Overall, it’s not a bad flux at all—just make sure you know what you’re getting and whether a fully liquid flux fits your workflow.

Just getting back into the electronics hobby from a long hiatus. This is such an improvement from the flux paste I remember. The bottle makes it super easy to apply and you really don't need much. Great addition to your bench consumables. Highly recommend.

This liquid flux works well. It is not listed as one that requires no cleaning but cleaning the part after soldering is easy with some isopropyl alcohol.

Works great. No mess.

Works great but in no way is this "No clean." It dries pretty solid, and does not come off easily unless you heat it up again. I had to stop using QTips to clean it up becuase they would leave tons of fibers on the board. Also any that spills on your mat will not wipe off easily. Again, it works great, but leaves a frickin' mess.

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

Used on small copper sculptures...applied with a small brush. Good coverage and allows solder.to flow.so much better

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

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.
