Not accurate

My initial review didnt do this justice. This is absolutely the worst hr monitor out there. Ive watched it spike from 77-190 in a matter of seconds for 40 minutes straight. Ive trained for 2+ hours and gotten 15 minutes of data. Save your money.

Im an avid elite OCR. Im on my 3rd one now and this works sporadically at best. It loses signal, closes down, stops tracking mid workout. Only plus is that it tracks to my phone. If you want a solid hr monitor try the iron man chest strap.
