Great addition to my GPS

not necessary -- but thought it would be a nice addition to help hold the Garmin & not loose it.

Great addition to etrex

Great addition to my Etrex 20, just clip on and go, worth the extra $$$ for the convenience.

A versatile addition to the Garmin Dakota.

while it *should* be a great addition, it positions the unit upside down for anything you might actually want to use it for.
