I’ve had the trackers for three years now, they’ve been dropped, kicked, flown out of the wraps and landed behind the lockers, sweated on profusely, batted around by the cats, charged and recharged, and they are still going strong. Great tracking, and the intensity metric may be a bit opaque, but its not how they measure, it’s about measuring consistently so you can track progress. I go for 80k intensity per month.
I do wish they would allow for posting results on their website so I can see how I compare. It seems a natural for interactive community activity and competitions. Can I do one minute of a semi-pro’s three minute workout?
Rolling up on my 400,000th punch, if I have the math right, and the trackers are hanging in right with me! Great job.
