Brassard connecté Index Sleep Monitor L/XL - GARMIN

It’s been six months or so, and at night I forget that it is on. The battery life is good, and as long as you throw it on the charger, it will quietly and comfortably collect your sleep data without a clunky watch

I purchased this sleep monitor because I have a Garmin watch along with one for my girlfriend. We generality like the concept of having the ability to gage the quality of our sleep and track duration, but we've had considerable disappointment in the accuracy and consistency of these devices. From tracking sleep when we're obviously awake to time differences in the multiple hours to when we put the device on and when it said we fell asleep we've had to reset these devices many times to try and get them to record accurately. Even when it does, we often don't get the data due to problems with the upload where we get no sleep data, but our stress and heart rate days shows up in our daily feed. It feels like Garmin rushed this out and didn't even want to support/ improve on the software after release. It's not worthless by any means, but as someone who owns multiple watches, bike computer, bike radar, heart straps, etc. this is by far the poorest execution of Garmin tech I own. Especially for the price. My girlfriend has recently decided she's going to buy an apple watch instead to track her sleep.

I've been using this for a couple of weeks. My sleep is improving, not because the band makes me sleep better, but because it makes me more aware of my sleep habits. I have been able to make adjustments. I enjoy the expanded data, as well.

I bought the Sleep Monitor a couple months ago, to avoid having to wear the Fenix 8 during the night.

Generally speaking the data measured seems to be accurate.

From a wearable perspective, it is a bit uncomfortable when used during the night. The band should be more flexible and the plastic buckle designed in a way that is is more comfortable.

This night the device stopped working, requiring a disconnect from Garmin Connect App and a re-connection. Of course all sleep dat was lost.

Easy to use. Comfortable to wear. I don't notice it on my arm. It's nice to see how long you sleep and the different stages of sleep.

Only records data about 1/2 the time. Pretty disappointed with this product.

This is not a new device. About every 2-3 months it will not link up with Garmin Connect, and the only way I can get it back on line is to disconnect the device so it is no in Garmin Connect, then have it find the device again. I have a number of Garmin devices (computer, radar/camera/light, camera/front light, scale, blood pressure) and Garmin usually does not have this sort of problem. Battery life is also low for something from Garmin, typically 3 nights.

Need more detailed instructions for all basic functions of the device
