Excellent. Would buy again in a heart beat!
on 16 June 2015
I bought this to replace my Zephyr HxM and I chose this model for 3 reasons.
Firstly it's Polar, which is a long standing brand with a reputation for making top of the range heart rate monitors.
Secondly, it supports Bluetooth 4.0. For those who don't know Bluetooth 4.0 is the low power version of Bluetooth, this means the heart rate monitor will go much longer on a single battery than a standard Bluetooth heart rate monitor. More importantly (for me anyway) it also means it is less of a drain on your phone battery while you are working out - important for those long runs when every battery % counts!
Finally rather than being rechargeable this uses a single CR2025 button type battery. My previous heart rate monitor came with a proprietary charging lead which I could never find when I needed it, with this one I can swap the battery out in seconds. No charging connectors and a sealed battery compartment means this is also waterproof so you can use it while swimming, assuming you have a waterproof phone.
An added bonus which I wasn't aware of when I ordered mine is that it also supports "gym link" so if your gym has compatible cardio equipment then all the machines will display your heart rate without you having to grip the handles on the machine. Tried it at my gym and it works like magic, you start running/peddling/cross training or whatever and your heart rate is detected in a couple of seconds. You don't have to set it up or anything.
Battery life is good, I always unclip one side of the unit from the belt when I'm not using it and I've been on the original battery for months with regular use.
Accuracy seems to be spot on with no spurious readings or drop outs during your workout. Comparing workouts I've done using this one and using my old Zephyr this one is much more reliable.
Overall very happy, would buy again.
Two screenshots attached. One shows the consistent readings from the Polar, the other shows the drop outs I used to get with my old heart rate monitor.
