How long can it be used?
Since the pump stopper is used by
fitting it to the base of the pump,
force is inevitably applied to it.
Whether attaching or detaching it,
it experiences a certain amount of stress.
Therefore,
"How many times can it be used?"
"Will it break immediately?"
I believe durability is a
point of concern.
What I felt after actually using it
This pump stopper,
while light and pop in appearance,
feels surprisingly sturdy when touched.
It's not too hard,
nor is it flimsy,
and when fitted to the pump,
it gives a definite "stopped" sensation.
Even after repeatedly attaching and detaching it,
it didn't immediately change shape
or become loose.
Durability is affected by "how well it fits"
What I realized while using it was that
durability depends not only on the material itself,
but also largely on whether the size is correct.
If you force a stopper that doesn't fit in
height or thickness,
unnecessary force will inevitably be applied.
In this regard, since this stopper comes in a set
with different heights,
it's easy to choose the size that fits the pump.
As a result,
less strain is placed on the stopper itself,
making it feel more durable for long-term use.
What kind of usage would be fine?
-
Carrying for travel or gym, etc.
-
Everyday use at home
-
Repeated attachment and detachment
For such uses,
there seems to be no need to overly worry
about durability.
On the other hand,
-
Pumps with special shapes
-
Usage that applies strong force continuously
For these cases,
it's probably best to use it while checking compatibility.
Don't judge by durability alone
A pump stopper is not something
you attach once and use for a lifetime.
Nevertheless,
-
Doesn't break easily
-
Can be reused many times
-
Can be used with peace of mind if the size fits
I feel that these points
are sufficient conditions
for an everyday tool.
"If it stops properly
and can be used a few times, that's enough."
For such people,
this level of durability might be just right.
