Not up to Garmins usual standard! 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

It has worked most of the time for me. Manual and Garmin tutorial video are not clear as to how to use it. The tutorial says to hold your finger over the sensor to wake the device before sleep. It says, the light will flash white to let you know it is booting, then purple and vibrate to let you know it is ready to go.This does not happen. I have no idea how to tell if the device has started. Most of the time it tracks sleep. Sometimes it starts itself at 3am many hours after I have fallen asleep. It seems so odd to me that starting the device is so vague and unclear.

It seems to be more sensitive and accurate that the watch, but its still too early to tell if the data will be helpful

I would love this product if it did not irritate my skin to cause itching and discoloration. I dont understand how I can wear watches, chest straps, and other arm monitors, but this one irritates my skin. Is there anything that I can put around it and still give accurate readings?
