Quality leaves much to be desired, for the price but just okay

I was hoping to get a good stethoscope for a reasonable price (5-10). I think I can probably forget about. This stethoscope is the material ago really not very good - the silicone smells very strongly of chemicals, the brackets are not particularly "stable", the olive feel when wearing not good at. The membrane on the double head could be better. In everyday medical practice to measure blood pressure still acceptable if no ambient noise, to listen to your heart / stomach etc. rather unsuitable.

CONCLUSION: If you want a bargain and can live with the given quality, for it is worth (eg private use). Quite useless now but it's not .. but then rather grab for a professional application to a more expensive, high-higher quality model!
