Not worth it- you probably can use you phone for what this thing does.

Summary: This device does not do basic things that you would expect it to do. It says it has the ability to mark 5 points but you can only use these 5 point to go find your car or other things- you can't load the points on your computer to find your exact spots- the only way to do that is to get a pencil and...
Summary: I purchased this device for 2 purposes: (1) as a navigational aid when accompanying family and friends on hunting or other outdoor outings and (2) tracking and sharing my regular hiking and bicycling expeditions. As a navigational aid the system is slow but reliable.
Summary: Does what we need it to do to meet the requirements of our State logs. They are not however "very rugged". We have had to replace 4-6 out of the 10 we bought originally due to the LCD screen going "black" or getting bumped or dropped by accident and the screen cracking rendering them useless.
Summary: This GPS does exactly what I wanted - tracks altitude, distance and temperature, and after the fact maps out where you went. However, it requires a standard USB input, so I bought a Surface RT since iPad and Kindle don't offer USB.
Summary: It is a basic unit, but it seems to get the job done. Have not tested it in the woods yet, only around my neighborhood and park. This upcoming hunting season will determine if it is worth anything.
Summary: Bought the unit for a trip overseas to mark locations of cars, hotels, etc. At times, it took 10-20 minutes to locate a satellite (even in wide open areas, with clear skies), Compass was useless, and constantly pointed in wrong directions.
