This little device fulfils most of the things I would want from a GPS handheld. Good battery life, clear and easy to read screen, reasonably intuitive menus and fairly inexpensive to purchase.
One small fly in the ointment however. The odometer which holds the sum of all the trip distances can only be reset to zero by performing a complete reset of the entire unit. This action will result in loss of all your personal settings and any data you forgot to back up. Not the end of the world but a bit inconvenient.
Also you may find spurious way-points being entered while the unit is in your pocket or your backpack every time the joystick presses against something hard-ish. Again a minor niggle but something to be aware of.
The internal memory cannot be supplemented but is sufficient for logging a day or so's outdoor activities. Don't expect too much from the built-in "map". The device specification scarcely mentions it, but even this simple map 'of the world' has its uses.
Overall this unit is a pleasure to use and, minor niggles aside, I really have little hesitation in awarding it five stars for build quality and functionality.
Enjoy.
