I bought polar m400 in their website for my boyfriend ' Christmas gift. When i opened the outer package box, it was already ripped open. I knew it was a returned item.  He told me later he thought same thing but didn't want to embarrass me.  When he tried to set up the watch, it was already set up with  previous owner's information and wouldn't let him input his info. So he tried to call and email sport check but no answer. So he downloaded mannual and did factory reset which allowed him to set his info. When i heard that I offered him to return and get a new one but he didn't want to go through that again. Product seems fine but I spent over $150 total over my budget to surprise him and it ruined my plan with embarrassment. I will never buy anything from sportchek online again!
