I need a bit more comfort for the hard floors. The plugs do not charge both ports at the same time. Great hooks! Specially for hardcore music lovers grab it. I was able to fit both my daughters shoes in this. I bought this speaker based on the reviews and Im not sure all the positive reviews are warranted. It was never outside, or abused or dropped. It’s built well and he says it is very comfy. After extended walking over rocky/uneven surfaces the rubber on the bottom of the shoe may start to peel off under the arch. I’m a big believer in the Vanicream brand for myself and was very excited to see they have a baby line as well.
