Best home oximeter

[stevelk9999]

1. We have the ring 02 and it works well.  For some reason, the recent oscar app seems to show the 02 sat input only on the summary sheet and not on the main graphs> Did something change or are we doing something wrong?

2. In any event question 2 is whether or not people have found other oximeters useful ( though not necessarily connected to OSCAR or Airsense)
  Mosimo Radical 7 and Contec CMS70A both go cheaply on ebay.   the Mosimo is a standard but the contec is pretty new.  Any thoughts?

The Welleu line of products are well thought of, including the Ring O2 you speak of. 

Contec also has a lineof products that are well respected,

 I am not familiar with the Mosimo product line.
