This is purely for informational purposes, and I'll answer questions if anyone has them.
What I liked about my Venu:
Battery Life - Lasted a long time, LONG...time
Durability - Handled abuse in and out of the gym
Comfortably - Didn't weigh you down and the ability to change the band is helpful.
HRM Tracking was decent once it got settled in.
What I ultimately made me return it
The OS, plain and simple is not for anyone looking for a "smart watch" at all. So many lags between screens and erratic decisions, anything not tracking my HRM was shady (sleep, steps..)
The screen was not utilized, get the vivoactive 4 and save $50 and get 1+ days more battery life, there's no need for the screen if it's not going to be used and lose 1-2 days of battery life.
Smart watch settings will never be where it will compete with current smartwatches who are trying to be fitness watches (Looking at you Samsung Active).
Erratic BT connections and Sync settings, why is it so slow and why couldn't it handle past 23ft of BT connection.
The buttons seemed backwards, back on the top? Weird.
Lack of community support, this forum, people have issues. I put in no less than 5 requests for additions and not even a confirmation it was received.
What did I go with?
Galaxy Active 2 LTE, not for cell, but for the 3 days of battery life, extra memory, smartphone integration, decent HRM when it's in place and the ability to integrate with many other features in my Samsung Note10 platform.
Does any of this matter, nope. As an avid fitness person and tech person by profession, I like control over my device and the lack of flexibility with the faces/OS and gritty setup makes it a pain to work with and for $400 it should be OOTB functional and intuitive.
Hope it helps.
