Charging is simple and quick, with around 2 hours to a full charge from empty, but a quick 20-minute charge will give you around 4 hours usage. Anyway, this replaces that, but I already had to adjust it about one Velcro patch tighter as its just that much too long. Qualità che rispettta le aspettative, molto belle. I love them but need to be careful with size Im. The holes and hardware didnt quite line up, making this a little difficult to assemble. I prefer the regular width as opposed to narrow and find regular width harder to find. And what is sheerness? I got the feeling pretty soon that these tangential topics were merely page fillers for what would have been an otherwise shorter book (202 pages). With that said, it doesnt look like it was used for long as it is a white controller and there are no noticeable stains from use. BUT I ordered this boot 1/2 size down, size 8.
