Pros
|
Single Stethoscope Unit. Does a pretty good job of amplifying. Ear tips are comfortable. Has Bell and Diaphragm functionality with visual indicators.
|
|
Cons
|
With stethoscope in ears, can’t see buttons to turn the unit on and off. Easily mistakable button selection. Turning on stethoscope while in ears produces a loud popping noise. Ear tips broke off during normal use during the testing process. Inconsistencies in powering up related to button pressing. Visual displays are confusing when switching between Bell and Diaphragm mode. Only works in 2 minute intervals.
