Horrendous customer service. Pulsetto charged me for the Premium subscription that I never activated or used. This was 48 days after I placed the order for the device, so the timing makes no sense, even for the free trial I never activated. I tried getting help using the customer service email, but that was a complete waste of time. I then tried getting an actual person to help, but the phone number I found online was disconnected. I simply gave up.
