Very well made product, with excellent sound quality and I loved the wireless charging feature. Overall, great improvements from original device. However, it did not work for me very well in my practice as a pediatrician. The device is too bulky to use on anyone younger than 7-8 y and hard to maneuver around clothing. The stethoscope also transmits too much noise from touching clothes, patient moving, etc. The lack of an analogue option meant that I cannot use it to check manual BP. It is also too bulky for that purpose. The electrodes would get cold and startle the kids when I'm trying to auscultate. I have to unlock the phone and open the app anytime I need to record and there is no way to do it discretely.
