I have a Vivoactive HR and love it except for the weak vibration when receiving notifications. I can barely feel it and miss calls frequently. I've set the alarm every night for a week and I sleep right through it.
The Forerunner 235 does everything I need a fitness tracker to do and I would pay the difference if I knew the vibration was noticeable. I had the original Vivosmart and the vibration would wake me from a deep sleep. Forerunner 235 owners, does the Forerunner 235 have a strong, noticeable vibration? What about the 230? I'm not adverse to wearing a chest strap for HR and all day HR is not important to me. Thanks.
