Its a bicycle pump that actually works, surprisingly hard to find in Taiwan.
As is usual when I find a product I like, the local Decathlon branches in Tainan have stopped selling it. Presumably due to lack of demand.
I asked if they had it elsewhere, and got the standard “meio”, but, while probably true and its been dropped from the range, that sometimes just means “I can’t be arsed”
If y’all are in your local Decathlon, could you have a look?
It is /was the “classic” “simple” “traditional” model, that looks like a bicycle pump rather than a ray gun.
