I have have some reservation after read the worst review -lrb- that it be too big on the wrist , the speed be erratic , it take too long to get the map etc. -rrb- . it be true that it be quite bigger than a watch -lrb- but then who expect a small size ? -rrb- , but the size be not prohibitive . the forerunner pick up map quite quickly -lrb- although I must say that I do try it in a small town with not many tree or big building -rrb- . finally , the speed be always accurate . overall , I find this watch a great exercise tool outdoors . I can not vouch for its software as I do not use this function . one thing be that it be clear the price go down . I pay $ 150 and now it be $ 128 . as with all electronics , the more you wait the less you pay .
