These are all minor but would put it over the top. Another positive of this experience: not once did the company hound me to change my review. This is a complete ripoff. The touch for volume up and down is nice. YOU WILL NEVER WEAR ANY OTHER SHOES. The hanging handle is also pretty convenient. Replacing the port would be quite expensive and eventually inevitable--to be avoided. The S4s will be relegated to the good times - the milk and honey times - the times my wife does not have them. 4 reflectors were tapped on. So, I don?t slide on hardwood floors yet the bottom treads aren?t deep so that won?t damage carpet.
