Finally a sleep study test that's easy to get so small and comfortable to wear! As a light sleeper disturbed too much by other contraptions, I'm going to finally get an accurate sleep study this time. The app is super easy to use too!

I can sleep for an hour at a time, it is so awful just getting thru the night. This is supposed to assess my condition with a pulse/O2 monitor? It didn't work the first night, and didn't alert me to any specific issue, and didn't alert that there was an issue till the morning. AFTER 8 hours of active monitoring, it then tells me, its didn't work but i can try again. WASTE OF TIME. Waste of insurance.
