I upgraded to the Venu 3 because I could check ECG to assure AFIB hadn't returned. I am 74. I was amazed at all the features and really like the Open Water Swim feature that wasn't available on my previous model. The sleep tracking is excellent. Unfortunately, I lost it on a boating excursion during a windy rainstorm somewhere into the lake while struggling to control the boat during docking. It could have been out in the 30' area or near our dock. Couldn't find it despite the crystal clear water. So I bought another one. After 2 months of being in the water, my son found it under the dock in about 5' of water. Cleaned it off, put the charger on and it lit right up and immediately had the correct time. It is working like new. I now have one for "work" and one for "dress" use!
Bought this around 4 weeks ago, and I am impressed at the features it has. GPS is accurate, heart rate, pulse ox, ecg, sleep coach, etc... Sturdy and well built.
I really wanted to love the V3 and would have, had it not been for its inability to track floors or stairs climbed. That's right, there's no altimeter on this watch, even though there's one on the previous version. For that reason, I had to return it.
I received this as a birthday present and am delighted with all the features. There are several fitness choices, sleep information, and a choice of watch faces.
