Title: Unreliable, Strap Broke first week
Review: bought this about a month ago on Amazon. The first time I wore it I noticed that it was unreliable. It will give you accurate heart rate for about 30 minutes but then it fluctuates within 50 points back and forth. It is not reliable. I bought this so that I could train within my target zone but with this piece of junk you do not know where your heart rate is at any given second. It jumps from 140 to 220 to 88 to 100 to 200. Also, the monitor part that straps to your chest broke the third time I wore it so now I've just thrown it in the trash and will buy another brand..
