This is the second power bank I bought in past two month. The first one turns out the capacity is too big to travel by air. I got this one under 10000mAh. Tested a couple of times. Works great. Built in cables very convenient. Comes with a storage pouch good for travel.
positive

Useless, basically its like a kazoo for your nose, does not alleviate snoring at all, if anything it made by nose feel sore the morning after, and is easily clogged if you have sinus issues.
negative

This eyeglasses smells soooo bad. Smell nasty chemical. I would have kept it even if it didn't work for me as other people claimed. I washed them with soap and warm water many times, chemical smell wont go away, so it made me decide to return them.
