This Sleep device helps by opening up your nasal passage and making your airways to be less restrictive. The vapors you inhale, works great by helping relaxation, which helped me to fall asleep
Charging up was quick and simple as per instruction and it's recommended use is a minimum of 10 times but I've used it about 20 times and it still charges.
I don't use it every night, only when I find it hard to sleep and you really do get a great nights sleep.
The first time of use, was good but I did wake a wondering what was attach to my nose however it didn’t feel too uncomfortable.
