I recently purchased the Pulse and it has been very disappointing! I’m not saying that it is a bad product but I guess it just doesn’t work for me. It may be because as a drummer, I’m always moving, but I find it very difficult to feel the pulse. I have tried different settings and different locations (wrist, arm, ankle) and it just doesn’t help. I find myself focused more on trying to feel the pulse than keeping the time which messes me up more. I’m now glad that I didn’t spend the extra money for the core which I almost did. It’s back to an earbud with a metronome app.
