Got 10 of these for work, or were given 10 by a nice person. After 6 months of light use by young people and instructors;
1)All are still working
2)None are damaged or scratched
3)None have gone walkies
Why? Robust, easy to use, waterproof, big bricks! Young people cope no bother with them, even my fellow instructors manage to use them with a bit of tuition.
Connect easily to pc and memory map software.
Reliable, were used on an BSES expedition by an instructor to survey a glacier. Coped well with temp etc.
Well priced! Not an all singing all dancing model, but does what it says on the tin. I've not had major problems with loosing signal.
