Query: Broke after 1 day

Might have been the perfect storm but this power meter broke after 1 day but unfortunately my husband also went into the hospital for 45 days and when I finally got to checking it out to see if it was a battery thing or a broke thing, the warranty period was passed. Tried to email Medicus directly but they won't reply to anyone who didn't order directly from them. I called then and they won't talk to anyone who didn't order from them. I'm stuck with a dud and really don't know if this thing works for real or not. All I can really recommend is that you use it consistently for a week or two so you can take advantage of the warranty period if it does break.
