this be my second Garmin . I buy a 305 last year and have to return in less than a month as the battery would not last longer than 2 hour . this year I buy this 410 . I be return it . after just 3 week it freeze up with a blank screen and never work again . Garmin say to return it . but before I do I really like it . it be comfortable to wear . it acquire satellite in less than a minute . the touch bezel be very sensitive but once lock it work fine . I be not get another 410 . I would buy a Nike Sportband GPS but it do not have average pace so I 'll probably try a 610 . good luck with a Garmin ... they be not the highest quality stuff .
