The battery life is also good, I used them for a week without charging them! They fit my hand all the way past my wrist. On first use, this product didn?t lather WELL but you can see a slight white milky look coming out and a handful of small bubbles. It fit perfectly and Is easy to operate! There are no starter recipes or any word of encouragement for a person who has never touched one of these. Fit a little tighter than my old slippers which were very similar, but it just feels different and, in general, I think they are going to work very well. I received my charger just today. On the last two rides, the seat has constantly come loose. The textured surface is great. Very impressed with the quality and sound.
