Primacare DS-9290-PK Adult Size 22 Inch Stethoscope for Diagnostics and Screening Instruments, Lightweight and Aluminum Double Head Flexible Stethoscope, Pink

This is an excellent piece of workmanship - very low in price and great for work in the health field for basic heart and lungs sounds. I noticed that it didn't come with instructions, so for all the people who are thinking of buying this - you need to know that you can turn the head (hold tube at base of head, and simply twirl it) to get a better/different sound. To hear very clearly, simply place your finger over the hole on the top of the smaller head. Heart tones, breath sounds come in loud and clear. I am so pleased I found this again. I had an older one (might have even been the same brand) that lasted me for quite a while so was looking for a similar lightweight stethoscope that did not pull on the neck, or whose headpiece is so heavy that it became a burden to carry.Before I came to Amazon, I had bought 2 other more expensive stethoscopes in the past month, but they were so heavy and unwieldy, and I could not hear from them as well, so went to Amazon and found these. Very strangely enough, for my ears, this cheap one sounds so much better than those other 2 Prestige stethoscopes (the $19.00 ones). Actually, even better than my old vey expensive Littmans.Also, since the price is so cheap, I will not regret losing it TOO much (like my 2 previous (expensive) Littmans). Well, I suppose we all have different hearing and perceptions of what we hear, so this is my opinion. I do have friends who swear by their Littmans, but for me, this sound is very much clearer.
