It's a great device with great price and I already have recommended it to a few people. Pros: Great audio. It comes with stethoscope tubing. App is great. The charging pad is amazing and it is way better than plugging your stethoscope to a charger. I think it is worth the price. Cons: Can't export audio from your phone and you need to log on a website. EKG lead reading is too small and it's hard to make diagnosis so then you are forced to record it and look at it at much closer distance. If the EKG was amplified it would have been much nicer. My biggest problem with it is If you use Bluetooth headphones such as airpods to listen to the audio, then the audio and EKG pauses every 2 second and it becomes unusable. I can't say I recommend using Bluetooth to listen to patient heart lung with this device. I was a bit disappointed with this as I have another electronic stethoscope that I use my Airpod Bluetooth audio with and that works fine so I was really looking forwad to using my blutooth headphones with this. My guess is the input and output in this device uses all of Bluetooth bandwith so it can't handle the data. But my question is why can't the data be compressed and not be transmited as wave file?
