Eduardo Ramirez –
I’ve been using this stethoscope for a while now, and what I like most is how consistent it feels in day-to-day work. The chestpiece has just the right weight so it doesn’t slip when placed, and the tubing doesn’t tangle as much as others I’ve used before. The eartips fit securely, which makes long hours less tiring.
Rosario Dizon –
Clear acoustics but tubing feels a bit stiff, expected more comfort at this price.
