Bests & Worsts Reviews from Amazon

Firstly the price is prohibitive for any fitness tracker/smart watch. I could find no use cases that separate this watch from say 75 to 150 dollar offerings. Issues: 1. ECG is still not available at writing this. 2. VO2MAX is way off and innacurate. Tested it against lab tested VO2MAX and it was off by a mile. 3. Heart Rate is never correct, O2 sensor seems to give many erroneous readings. 4. Running assistance voice is annoying, voice operation doesn't work as well as competing voice service (siri, google assistant) 4. Watch is leather and drags on skin while running causing redness after first run. 5. I took 2 calls using this and both calls dropped, since then I just use my cell phone out of fear of it just rando dropping.
