Not suitable for DSi - requires DS to use pedometer - this was not clear prior to purchase. Only retains details of one user so cannot be used for the family. Games rather boring and basic. Sorry but not a winner - glad I did not pay full price.
Pack is well made and suits the purpose. Compact size ideal for those with limited kit and flexible strap arrangement also handy. Larger version may be needed for those with multiple or large additional lens and kit.
