The stethoscope is made up of 3 parts, the silver headpiece with white ear plugs, the black hose and a rather slight silver eavesdropping device. Overall, the parts have a good workmanship and quality nowhere I could find defects. Also from the optics, it also looks like a real stethoscope if it is also so only works show the test. In any case, it is ideal as a carnival accessories for a costume. Of course, I have also tried the same times if it works well. Unfortunately I only have a noise perceived and the noise comes when you ran the hose. My heartbeat I could only perceive sometimes very quietly, because the noise was too much. I could usually only hear my breathing, finger on the stethoscope or my finger joint, no matter where I have stated. The pulse then against one notices already clearly I think. But what do you expect at the price of just 5 euros and also also it is indeed in the title that it is rather intended as a carnival accessories, so it would rather have been a plus point when it would work properly. But I think you could use the product description a bit by expanding to minimize mispurchases you exactly and pointing. The only negative is that it is quite suppressed in the ears when it puts on because it is not adjustable and the ear plugs from a tough but lightweight plastic instead of silicon. I think it's still great to just the low price you have a great carnival accessories when you go as a doctor, nurse, etc., because it looks like one and still works part.
