I recently purchased the Essmetuin No Clean Soldering Flux Paste (4Pack) for various electronics soldering projects, and I am thoroughly impressed with its performance. This solder flux is a game-changer, especially for those who engage in tin soldering and work on circuit boards and copper electrical wires.The most striking aspect of this product is its "no clean" feature. It significantly simplifies the soldering process by eliminating the need for post-soldering cleanup. This not only saves time but also ensures that the soldered components maintain a neat and professional appearance.The consistency and quality of the flux paste are excellent. It adheres well to soldering surfaces, providing a smooth and even application that greatly enhances the soldering process. This consistent quality is vital for precision work on circuit boards and electrical connections, where accuracy and reliability are paramount.Another commendable aspect is that the Essmetuin flux is lead-free. This makes it an environmentally friendly choice and aligns with health and safety standards, which is increasingly important in electronics work.Each pack in the 4-pack set is a testament to the thoughtfulness of packaging. The containers are well-sealed, ensuring the flux remains fresh and free from contamination. This attention to detail in packaging reflects the overall quality and professionalism of Essmetuin as a brand.In conclusion, the Essmetuin No Clean Soldering Flux Paste is an outstanding product for anyone involved in electronics soldering. Its ease of use, high quality, and environmentally friendly composition make it a top choice for both hobbyists and professionals. I highly recommend this product for your soldering needs; it truly enhances the efficiency and quality of soldering work.

This flux does everything it needs to. It holds up for a long while without burning off, and when used with good solder, leaves it almost unnaturally clean.I'm my testing I could keep a ball of solder completely shiny and flowing indefinitely, as long as it remained in contact with this flux. It was less effective at refreshing already dry joints, but it still preformed acceptably in these cases.At temp it's easy enough to wipe away, but it seems highly resistant to common organic solvents, and entirely unaffected by soap and water, so if you need residue free parts, a qtip or adsorbent material is essential for removal, and it must still be hot if this route is used.Price is just insane for the volume that you get. Will get MANY uses out of the multipack that I did

I didn't expect much from this flux tbh. It is so nice to have a syringe style flux, it's much cleaner. That and you can control the flux much easier.The performance was better than the weller flux or the other stuff I have tried.The price is fantastic for the amount you get. You also get multiple tips (4 metal and 4 plastic).Easy recommend.

These things work perfect! Makes my soldering a whole lot easier and better. I highly recommend. The precision needle points help put the paste exactly where you need it. It should last to cause you don’t need but a super tiny dab. I highly highly recommended.

Works well

This is exactly what I was looking for. Great deal. I love the convenience of the different tips. If you're on the fence, just get them. It's a quality product.

flux works great and flows smoothly makes my solder go right where i want it, cheap too

The Seller was very fast in the delivery and the product is awesome, the weld runs easy and I used it to weld iron with copper. I recommend !
