It charges fast as I had to do before first use. They fit on predrilled holes on the longitudinal bars, so you cannot choose their position. I think the best part are the lights on the front that show what is charging- the watch, phone or AirPods. One for son and one for daughter. je suis enfin soulagé, l’expérience sonore est là. Firstly, the box was damaged (indicating that it was not handled properly). I dont think it can get any smaller for how much power it can deliver, but the size and portability is great for everyday use and travel. I got all black, and around the soles and details theres lots of visible clear glue and just little details that you would expect to see different for a shoe that’s $120. I can hear this thing through out the house with 1/2 to 3/4 volume. Not bad for glass beads!
