Fits FaceLake oximeter...
...but put it on its side to keep the power button from being depressed.  It looks like it wouldn't fit but it zips shut without a problem.<br /><br />I put it face forward (on its side) and the button is not accidentally depressed.  I bought the case because my oximeter was always turning on when left loose in the zipper pouch of my purse.<br /><br />I'm also able to carry two spare AAA batteries in this case as well.<br /><br />I am very satisfied with this purchase!
