Works Great
I had a small project to complete and this worked great. When it first arrived I was concerned that by just looking at it, it looked dried out. However when I used it, I was proven wrong. It came out great and the applicator helped place right where it was needed.

Well packaged (easy
We purchased for our field solder kits. It is perfect and will be purchasing for the labs too. 1. Extremely precise application of flux 2. Much prefer paste over liquid flux, so much more control and less mess 3. Flux also makes very little mess 4. Plungers can be pulled out and reused and tips can be taken off and reused which is great for our field kit where we have to pack the flux up often without mess and waste. Perfect solution!

Works great
Cleans soldering surfaces very quickly and effectively. I am very pleased with this product, I cannot say anything about its corrosiveness. Since I have been using it for too short a time, I am pleasantly surprised by the effectiveness of this product. I recommend it to anyone who doesn't want to waste time looking for a good soldering paste.

Great price for no cleaning flux
I used on my old Xbox 360 red ring of death. Put the flux per suggestion per YouTube video and use hot air soldering station to reflow the solder. I only clean the remaining flux around GPU and CPU. Hopefully the unit will last without corrosion under chips. Manage to fix the red ring of death (phat Xbox 360)

Works as a flux, some smoke.
I used this flux for surface mount chip removal and reinstallation. It comes in a standard syringe with a long applicator tip. The flux dispensed easily, and I spread it out using the included brushes although it really wasn’t required to do so. The flux worked well to keep the joints clean when unsoldering the chip and there was little noticeable smoke. Not sure if it was the new solder or the flux but when the chip was soldered back on there was quite a bit of smoke not seen before. The flux is no wash but be aware once heated, this flux got stickier than others used. Overall, the flux worked to solder/unsolder using hot air and is comparable to other fluxes at the same price.

I don't know about "no clean" but this stuff cleans up fine with IPA and I would imagine your regular flux cleaner. It is pretty thick but that's OK as it comes out of the tip slowly. The packaging is first rate with caps on both ends. Good stuff!

Good product, decent price.

Not much to say really, this kit is pretty cheap for what you get. I don't solder on a daily basis, so this amount of flux will likely last me years. The wicks and brushes are also a nice addition and come in handy on occasion when desoldering surface mount components. Great stuff!

This stuff makes all soldering jobs so much easier! Easy to apply and I haven’t messed up once since using it. Even managed to finally solder some smd components
