Review: Good inexpensive flux no need for a brush - 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
Review: Works great when I remember that I have it! - 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.

### ⭐⭐⭐⭐⭐ Soldering Newbies Beware! You may want Clear No-Clean Flux Instead!
*by G***G on August 27, 2025*

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.
