Over all I'm happy with this model of GPS. I am a little disappointed in the road maps included with it. Pretty sparse. But I didn't buy it for roads anyway. It just sucks that you have to drop another hundred or two on a map pack if you want accurate road maps. That said, this little baby can take any jpg image and float it over the base-map. So for example, you can take a photo of a map you may have, and line it up using Google earth, and it will show up in your GPS accurately. I have done it, and it is a fairly simple process.

This thing worked just the way I wanted it. I am using a 5D MK II, and I purchased it in order to to time lapse videos. Much cheaper than the Canon TC-80N3 model. Very happy. I don't know how long it will last, but it feels pretty solid. Required 2 AAA batteries.
