Finally, this little tool came. I always gripe about having to use the solder paste and resin flux syringes which were too long for my thumb. Not using them frequently means the plunger is always at the high end.
Two years ago, I was tempted to get some of those aluminum plungers which were quite abundant. Then I realised, I would be merely swapping out the plastic plunger for a metal version and the problem would still persist.

This was the dispenser which I really wanted. Looking at the construction, it has auto reset so you do not have to twist any bolts. But the downside was, chances are, you’d need to transfer your solder paste or flux into their own syringe. And it does cost a lot. Then again, you’re buying for their solution.
The first thing I need to do is to unscrew the long metal bolt and then turn it upside down.
So, this dispenser is quite fun to use and I might get a second one later if I need to swap the syringes often. By now, I am very sure the metal versions would be on the market as well.
