The connection with my iPhone was very smooth and easy. There is no lag and the sound quality is superb. It last days with full charge. Looks very sophisticated.

I ordered a size down since I like the bands to feel snug and secure, but it was wayyyy too big. I cant even wear them because they slide down or roll up. Its unfortunate because I was so excited to order them! The material on the band also is not sticky enough to adhere to the pants. Wish I would've returned when I had the chance.
negative

I have a deeper appreciation of Grant, the man, than Grant, the general, as portrayed in other histories. The relationship between Grant and Twain has also been under-recounted. This is also a good source for filling in some blanks in the American story.
