Is even getting an AWU2 from another country by online ordering banned?
Need someone going overseas to do a bit of shopping for you
The O2 sensor is not the only reason I returned the AWU2.
To track my sleep I have to set a sleep mode with a schedule, and it will only track sleep during the set schedule. Or... I could put it in sleep mode manually every night when I go to bed, and take it out of sleep mode every morning when I wake up. With the GWU, I just need to go to sleep and wake up, and it tracks my sleep automatically.
The HR zones on the AWU2 force me to use "what they think" is my MHR, and set the zones based on HRR. The only other option is to just set custom ranges for each zone. The GWU gives me the option to use the standard 220 - age formula, or set a custom MHR, gives me a choice to base the zones on MHR or HRR, so no need to set a bunch of custom zones (the way it should be).
The AWU2 gives me a VO2 max in the low 20's, and I know mine is in the low 30's (based on Garmin devices that I have used for years). The GWU gives me 36 (which is probably a little higher than mine actually is), but over time it will probably get more accurate.
When I log my medications on the AWU2, they don't update in apple health, and I then have to update it there too. logging my medications from the GWU works the way it should.
There are other things too, but these are the main things for me. The only things IMO that the AWU2 has the advantage over the GWU is that the HR and GPS on the AWU2 seems to be (arguably) very slightly more accurate.
Other people may not find these things important, but I do, so for my use case, the GWU is the better choice for me.
