I have tower of power. " I agree with other reviews that these sandals last a long time, mine usually last a year, but in Arizona, Im afforded more time to wear them without getting cold, and although the old ones look bad, theyre still comfortable. Its a quality shoe, made of solid materials (made to last) but I wish theyd take into consideration that these dont need to last and make them softer and more flexible. The pairing was easy and the sound is excellent. Being able to bring this product with me when I go out is of limited value, so the "portable" nature that likely drove the battery compromise isnt worth the tradeoff of horrible battery life and exceedingly long recharge time. These are going back immediately. They will grow with her for awhile, which is great. It is so comfortable and soft. La scarpa corrisponde alle caratteristiche, ma ha una pianta piuttosto larga. The Hold Up bike rack is very sturdy.
