Two months later ...

I just ordered two of them today, local stock
Greece.
KING TONY brand, this has portfolio of general hardware tools.
Therefore their products they can be found
at general hardware stores alone, next to painting brushes there is parked and this 6BD22 .

In a few days, I will receive my order.
Then I will take apart my 20 years old similar design, and I will demonstrate of why it failed.

Distinguishing of Taiwanese goods these days, this is a challenge.
KING TONY brand, this has Taiwanese origin, all their tools, hexagon keys and others, all Made in Taiwan.
This specific Taiwanese product design, this last long at my hands for two good reasons. 1) Frequent cleaning and tube lubrication.
This expands the life cycle of O Ring at 10 years at least.
2) I do not use the nozzle alone, I am adding silicon tube attachment. I am collecting silicon tube from damaged coffee machines, and stream hot irons.
This silicon tube attachment, it improves vacuum force, additionally its de-soldering spot this is fully covered, even microscopic portion of solder, this is removed.
I ve never paid so to buy a spare nozzle in my life time.
I am today twice as happy, I got the ultimate quality for a reasonable cost, and I did leave the Chinese copycats starving.
When you need tools, you should visit a tool maker.
When you need toys, you should visit a toy maker.
If you cannot perform this discrimination in your brains cells, you will be always at a loss.
