agree. though to be absolutely technical about it … its not really “needle free” … there is a needle, a small one … similar to one used for pricking a finger to draw a drop of blood for sugar checks. now as a consumer who has experienced both … i’d say it hurts the same. a pinch is a pinch is a pinch after all …
but there are definitely ppl who’d prefer the “needle-less” method.
for now there is no utility of this system in hospitals though (ER and inpatient).
