I bought this scope to replace a Prestige Clinical I Stethoscope that I recently returned. This scope is worth every cent of the higher price. I could barely hear anything from the Prestige, but can hear sounds much more clearly with this scope. Plus it is much more comfortable, there are fewer "static" sounds from touching the tubes, it comes with extras and a clearly written instruction manual, and it feels built to last. It is more adaptable to different needs and would be suitable for anyone whose hearing is not 100% or works in somewhat noisy conditions. All in all the Prestige Clinical I Stethoscope seems a cheap knock off of this scope.
