I think I like it. I used to wear Garmin Phoenix 6 and these interchangeably until Phoenix's wristband got damaged and I've been wearing mostly ScanWatch ever since.

It's minimalist design, not distracting, and good looking design too. It's neat.

It has subset of fitness functions Garmin has, but still a whole lot of them. Has the usual step counter. The main focus of the watch is on health functions. It has EKG, can record it into a PDF file and share it with smartphone app. Can detect Afib events. Got those a couple of times, but I can't testify how good the detection algorithm is. I do have minor arrhythmia, though.

It also got Oxi meter, FDA certified to detect sleeping apnea. That was the reason I bought it, it was a panic buy. I've got problems with breath, I was hypoxic when waking up. It could be due to COVID, could be for other reasons. Never got anything detected by the watch, though.

The battery lasts 25-30 days depending on settings. Oxygen tracking during sleep shortens the life on charge, but not by much.

Thing I'm missing from Phoenix is Garmin Pay. If I would go outdoors hiking it would also be compass, tracking and GPS. Occasionally the music player, if my phone's battery will get discharged. But I feel at ease without feature overload. Most things I used in Phoenix were step counter and breathing exercises, both present in ScanWatch.
