I have been working on electronics all my life and really didnt see a need for fluxwell to my surprise i did need this. i thought i would give it a try and see if i was missing anything. and as stated before. this was just what i needed.if you think you do not need flux to work on electronics. you are going to be amazed when you finally give it a try.I recommend this to everyone the works on electronics.really good product.

As others have said, the flux is very good. It's got a fairly high rosin content and it's very active at lower Temps, so it works very well with lead or lead free solder.The two sizes of tips for each syringe is very welcome. For hot air rework this flux is very effective.The big complaint is the plunger for the syringe. It's the correct size for the syringe, but it doesn't have the normal rubber plunger on it. It's instead just the plastic part that loosely sits in the syringe and pushes against a pre inserted plastic plunger. It doesn't work well at all and you will end up fighting with the syringe to get the flux out, and then it will be in uneven amounts.The syringe was made to be used with either an electric dispenser or a manual dispenser. The plastic plunger was included for unknown reasons because it just doesn't work with the syringe the way its setup.I have both types of dispenser and it works well with both. You can find the manual dispensers here on Amazon for between $10 - $20, and they well worth it. They give far greater control on how much and precision placement of the flux.Electric glue dispensers with foot pedal control can be found here but are needlessly expensive. Look elsewhere for them in the $60 range at 120v. These syringes will work fine with them.

Current version still comes in the poorly designed plunger/syringe. The flux itself is functional but be prepared to glue the plunger handle into the actual plunger "plug" inside the syringe unless you're ok w the dexterity check required to hold it all together while dispensing it. I used a two part epoxy to glue the handle into the back of the syringe stopper and that seems to be working fine. wish I didn't have to do that but still giving four stars for flux quality and value.

Package arrived on time. I used it first chance I could. The solder paste worked as described, easy to use, thickness was durable, and manageable with a easy clean up. This will be great for working with and teaching my grandkids.

I needed a way to apply flux to circuit boards while unsoldering components. These tubes allow one to apply just the right amount of flux to just the right place.

This stuff is not bad at all, works well and helps the solder do its thing, kind of auto pilot little effort needed from me.

Wow - I've been soldering for about 45 years, and honestly, didn't think I was missing anything. Well, I was wrong! I had recently watched a few videos on YouTube regarding the use of solder flux, so I thought I'd try the product. I can't believe I've been soldering so many years without the substance. It made removal of Surface Mount Technology (SMT) devices, cleanup of solder pads, and re-installation of SMT devices so easy with my Weller. I'm really happy I've come across these videos and selected this product!

The plunger doesn't connect to anything so you essentially are using it as a pusher stick when you want to get some flux to come out. That may sound fine to you, but I assure you it is quite awkward. The flux itself has worked great for me.

Good quality, wirks well.
