Lovely product. Very innovative. Most importantly I would like to emphasis the thoughtfulness and care that went behind designing this product. You just put in the power bank once and you needn't remove it. This is the perfect companion for a traveller, great for train journeys, bus rides, flights and travel in general. The massager is wonderful, and extremely relaxing and stress relieving while your in transit. It is a brilliant new innovation, but the bag is also very spacious, I could theoretically keep to laptops, couple of books and other accessories and it still won't feel full or overpacked. The charger is lovely and useful add on for people on the go. We can't live without our phones so this is nice!
