Let me start by saying I've been wearing this watch for over a month now, and it's completely changed my relationship with smartwatches. Unlike those bulky, distracting screens on your wrist, the ScanWatch 2 looks like a proper timepiece - I've gotten multiple compliments from people who don't even realize it's tracking my health data.
The ECG feature is what sold me. As someone who occasionally gets palpitations, being able to take a medical-grade reading in 30 seconds gives me real peace of mind. The first time I used it during an episode, seeing 'Normal Sinus Rhythm' pop up on my phone was incredibly reassuring. Though fair warning - you need to be statue-still for accurate readings.
Sleep tracking has been eye-opening. Waking up to see how much deep sleep I got (or didn't get) explains so much about my energy levels. The temperature tracking is fascinating too - I noticed spikes before coming down with a cold last week. It's not giving exact degrees, but seeing those fluctuations is useful.
Battery life is solid at about 3 weeks for me (not quite the claimed 30 days), but that's with continuous heart rate monitoring and weekly ECGs. The lack of built-in GPS is annoying when I forget my phone on runs, but the trade-off for that sleek design is worth it.
My only real gripe? That 'seconds' hand that's actually a step counter feels like a missed opportunity. On bike days, I'd rather see activity minutes than steps. But overall, this is the perfect balance between smart functionality and classic watch aesthetics.
