Doesn't work well for tracking in your sleep.
8 of 19 found this helpful This pulse oximeter does basically what it's supposed to with exception to tracking sleep. It WOULD do this if it would stay on your finger. It doesn't clamp to the finger tightly enough to stay on your finger well enough to make it through normal tossing and turning of sleep. With exception to that, which was one of the features I needed, it does check your pulse and O2 levels as it's supposed to.

The timer does what is expected.
Works as intended, so far. I'm using it as a timer on an upright freezer.
