Title: not working properly
Review: we have had trouble from the beginning with this product. i got it to train for a marathon and it has not been accurate at all. the distance and pace per mile jumps all over the place from a 6 minute pace to an 11 minute pace when i know this cannot be the case. i am an established runner, the pace differenc is not accurate. i have the original box and need to speak to someone or send it back for a replacement.
