This newer charger doesnt get nearly as hot and has had no problems turning itself off when not being used. I have foot problems, and these are very comfortable, and last a long time. This pulldown rope for the price was way beyond my expectations. Once this starts, there is no way to brace the pole from bending further and eventually falling. Leider kann man das Fell, entgegen der Beschreibung nicht einfach herausnehmen! It made me look rounder which Im not although Im a size 14 in jeans, I have some shape. They fit perfectly and keep my earbuds in place, even while running. I did experience this, to the point where there was some bleeding after a day wearing them. Other than that, it is a solid product. but just what I wanted.
