I've been using the Gear S2 since it was launched. Bought because the Gear S2 was finally out of service. Overall, this is an effective and inexpensive replacement. However, the instructions are not clear. There are a couple of screens whose purpose I don't yet know. Bluetooth works great and matches my hearing aids. When I'm on foot it tracks very well and has a pause feature which I like. The app integrates well. I don't think the heart rate monitor and blood pressure readings are accurate. I use a separate sphygmomanometer and it fluctuates wildly and the doctor's readings seem more consistent with the device. I have a pretty good idea of what my heart rate should be at different levels, and these readings vary significantly. Those are my only two concerns, and since I don't rely on them, they don't matter to me.
