My Nightowl Testing was very easy to assemble on my own on my index finger, in the comfort of my own home. Did not bother me one bit, I slept very good. If it were to be the old fashion way with staying over to sleep in a clinic, with all those wires attached to your chest and head. Especially sleeping on only your left side, I couldn't. This Nightowl device is lightweight about an inch long and cute. Lays on the tip of your left index finger secured by special tape. I like this new technology.

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!
