[Equipment] Wellue Checkme Max O2 Watch

[mu50256]

I bought the Wellue Checkme Max O2 watch at the end of July and I am starting to find the results to be very inaccurate.  This has my O2 dropping into the low 80's/upper 70's at night multiple times, sometimes as many as 100 drops overnight.  My heart rate is often down in the low 40's, rarely upper 30's (I am obese and just starting to exercise so not enough to have an athlete heart rate).  I just had a sleep study Friday.  The sleep tech did say my heart rate did drop low, but my O2 didn't drop that much during my study.  I also have a Masimo MightySat RX O2 finger monitor, but it is not continuous.  I have started putting it on when my Checkme starts vibrating showing a drop and the MightySat is not showing these low drops, just minor drops, not even below 90, that seem to come back up quickly.  I am wondering if anyone else is using this device and having this issue?

Thank you.

No, but your experience makes the conclusion pretty clear. I did own the Wellue ring but got rid of it for the same reasons. Nothing beats a simple Contec or Beurer on the finger thingy in my view.
