tire.pump with Topeak pressure-rite adapter

. the Topeak`pressure-rite adapter is ingenious:
it has it's own pressure sensitive valve inside;
give it a pump to engage it,
then your pump's gauge's reading will be true;
finally release your pump's engage
and the adapter quickly releases pressure on the tire's stem valve .
. now easily unscrew the adapter .
. the adapter screws on easily, and has a rock-solid connection .
. they advertise it as getting into tight places,
and providing exact pressures;
but, it's also doing well at an additional use case:
since it's the pump's pressure that sets the adapter's stem depressor,
the pump's stem depressor never gets worn out .
. also, since the adapter's stem depressor is metal,
it never gets worn out either !
