I would recommend this product and plan on buy more colors. I was very hesitant to buy another pair, because many companies change their product and i was, well, afraid to part with my Tevas after 12 years of use! Meines Wissens gibt es übrigens keinen Unterschied, ob es nun Damen- oder Herrensandalen sind. I exchanged them for a size 10 and the fit was perfect. The recharging is done via a USB cable to your computer. Once assembled it seemed sturdy moving 225lbs around on it for presses and squats. forget it! Would buy again if they offered some more colors down the road. So, based on a few reviews on the LP140, I wanted to see if any of the old issues persisted in this newer model. Sound is clear but level of volume is not very high.
