I detest this heart rate monitor
, October 11, 2011
I still own a Polar M21. I loved it, still do as a matter of fact, even though I've had it since the late 90s. It displays what I want to see on one screen. I put my wrist near the transmitter if it's dark and it lights right up so I can see the screen. No button pushing. I did get tired of having to ship it back to Polar for battery replacements (I do not have an authorized service center nearby), so when the wrist strap broke in two, I decided it was time to buy a new one.
I have had the FT7 for almost two years now. The watch is bulky and uncomfortable. The chest strap is larger and protrudes more due to the detachable transmitter. To this day, I push buttons in hopes it will do what I want, but it never does. It did have an adorable little birthday cake on the screen on my birthday, which I missed the first year because I was on vacation. A few months ago, I was constantly getting "Check heart rate transmitter!" messages, which had happened all along but eventually I'd get the darn thing to register...which is not to say that it maintained throughout a workout. I'd often get so frustrated trying to get it to work again that it derails me mid-workout. Now, nothing I was doing would get my heart rate to register. I decided to replace the battery, even though there were no indications it was dying. Still nothing. Then I discovered this model also has a second battery in the chest strap! Ah ha! (So how did the old one work? Why does this one need a battery now?) I replaced it, for another $6. Still the thing wouldn't work. I discovered that I had been a Very Bad Heart Rate Monitor Owner after re-reading the instructions. I had never once washed the strap. So I did, and it finally worked. I was very happy, I finally conquered it. I began washing it once a week with my gentles, but now, two months later, I'm again having trouble getting my heart rate to register.
The M21 I could lick the backside of, strap on, and it always worked, without fail. I never once had an issue with it - ever. Now I'm just going to go see if I can get someone to replace the wrist band and forget I wasted the money on the FT7. Upgrades are not always a good thing.
