Terrible... avoid!, 19 May 2013
I bought this a few months ago as I was starting p90x and wanted to do everything right. This is one of the most useless pieces of plastic rubbish I've ever had the misfortune to own. After three months of trying to understand the instructions I still don't know how to use this piece of equipment. Sometimes it tells me I'm dead, sometimes that I'm at a heart rate of 400bpm.
Avoid this at all cost.
