Very comfortable HW - Addl SWFunctionality needed
on May 5, 2026
Posted by: Jon Paul
Epix gen 2 owner and the Sleep Monitor is much more comfortable to wear at night - it does its job well.
Would love to see some new features added
* In addition to setting alarms for specific times, would love to see the ability to set alarms for specific amounts of time - say 30 min for a nap, or 8 hours regardless of what time it is when I go to bed. (Thinking out loud - not just by wake-up time (7am) or length of time (8 hours), but by sleep need - Garmin connect has the information so why can't you determine when the user falls asleep and then calculate the right time to wake up?)
* Would love to see quick alarms that you can set once and then disappear after the alarm goes off - not every alarm needs to be saved.

Low SPO2

It's early yet but it helped with identifying a SPO2 issue while sleeping. Good data for my Dr to look at and schedule more tests

Better than a watch for sleeping
on April 24, 2026

I love the form factor and ability to get me sleep data without having to wear an uncomfortable watch overnight. However, the device frequently has issues where Garmin connect seems to forget it or random nights that sleep data just doesn't sync and that's why i'm only giving 3 of 5.

I’m two weeks into using this, and it’s much more comfortable than wearing a watch all night

I like it, but it resets if I wake up for more than an hour at night.

Worth it, but it can't be over tattoos.

Once I got into work - it works really well. The problem is it can't be over tattoos. So I moved it to my right arm on the inside of my arm. Comfortable and works amazing
