Stethoscopes purchased on Aliexpress

Visiting the Aliexpress website, I saw that there are some stethoscopes on sale at acceptable prices that seem to be clones of Littmann stethoscopes. There is an electronic stethoscope on sale, which interfaces with the smartphone, at a price of around €60.00. Has anyone had the opportunity to purchase and test them?

Definitely, NO and I don't! In general, I DON'T SUPPORT ANY OF THESE FAKE- AND/OR CHEEP-SELLERS! Just my attitude to this topic.

I always trust in original products, offered by serious and professional sellers on serious and professional sites or shops, independent of the category and if a product is too expensive actually, I wait and search for a special offer, price reduction, sale or what ever.

I found Littmann and MDF stethoscopes listed on eBay but that's not the place I would recommend to buy such a pricy instrument from. Same about AliExpress and the rest. I did ordered a stethoscope from eBay but just a cheap one and didn't believe it would ACTUALLY work. Surprise,it does but can't be compared to my professional stethoscopes.
