First of all, this is not a professional device. Only use for emergencies and as a first aid device. All medical conditions should be referred to qualified and practising professionals.
This device is easy to assemble and use. The materials are durable, although the total package feels rather short.
Easily recommended for inclusion in a first aid kit.
The stethoscope is ok for its price. It will do the job for home use. Not recommended for heavy duty or professional use. Arrives taken apart, assembly is simple, but does require some fidgeting and finger strength.
It's cheap comparing to other stethoscopes on the market and it's easy to put the pieces together. I only recommend for house use and not professional use! you can hear the sounds but not as clearly as you would listen with a professional one.
