So while I am not taking off any points for the speed (since it was a known issue before) I am noting it for any who need oinkers in a hurry. I also like how my devices do not become warm or even hot when you leave your devices charging for long periods of time . Unfortunately returning them. FIRST REVIEW: BEFORE THE UPDATE ABOVE: As far as it being able to sound up to 500 Watts Peak Power(I would say, that is very Questionable. My previous quicksilvers fitted perfectly well so i dont understand why these new ones have so much slack. I don’t think taller people could use it at all. Qualities include: a built in flash light, solar panel charger, radio, amazing speaker quality, easy Bluetooth connectivity, and a sos button. If you are going for a more realistic feeling system you are going have to dish out more money. The padding inside went flat within a week. I didn’t think I expanded it that much so I don’t know why it stuck to the inside of the shoe.
