The article is out of date. I used a Polar OH1. I liked that it had a memory. I liked the band. I didn't like the battery - I got 6 hours/charge, instead of the expected 10-12 hours.
I bought a Wahoo Tickr Fit. I wore a medical HRM for 3 weeks, and it was tracked by my Tickr Fit pretty well. Also the Tickr Fit gets a lot of hours/charge.
Another option to be considered along with the Scosche 24+, if you want to avoid possible discomfort with a chest strap and get good accuracy.
