Amztek Charging Data Clip for Garmin Forerunner

Works great with my Garmin Forerunner 405 (round-face) watch. This charger will work with other Garmin watches as well, as there are different contact pins for different configurations. Mine uses two of the four pins.

Says it works with 310XT in description - this is not true. It doesn't have the right pin configuration for the 310 xt. The pins on the charger do not correspond to the contcts on the301xt.
