Bought the case for my newly ordered Garmin Zumo 66o. I'm very happy with it: lightweight but rigid enough to offer good protection: it sits in my motorbike top-box or car glove compartment, and protects the Garmin from prying eyes or harm. Easy to slip into my pocket when I'm walking around.
My mistake? Of course, when the Garmn arrived I found it comes with the case anyway! Hey ho: fortunately, it also fits my Passport hard-drive, so nothing's wasted. I am determined to read accessory lists more carefully BEFORE making purchases, however!
