TomTom Bluetooth Heart Rate Monitor

I've used this heart rate monitor vigorously, and I emphasize that word a lot, over the last couple of years. I've used it in spartan races and other everyday activities and it has held up incredibly and I've only had to replace the battery a few times. Also, let me add that I sweat profusely, especially since I live in a very humid area.I have noticed that most of the complaints on this monitor involve the "strap" and honestly, I don't understand that complaint. I've worn this during activities that last over 2 hours and I never even realize I even have it on. Sure, I notice it when I initially put it on but I forget about it almost instantly.This has helped me more than I can explain and has held up FAR longer than I could have imagined especially with everything I have put it through.

I bought this to use with iphone apps and very happy with it. It connects to iphone when i activate bluetooth in the phone. I have not faced any disconnection issues over the one month period. This is my first heart rate monitor so I cannot compare but it feels comfortable.

My 1-year old Zephyr HRM died and their customer service ignored me, so I looked on Amazon and found & ordered this TomTom HRM. I use it for cycling. It worked beautifully. This is a smart Bluetooth device so it didn't need to be paired like other deivces. I use it with Moto G4 Android Runtastic and Wahoo apps and they found and connected to the sensor immediately. Just remember to remove the sensor from the strap when done using it so the battery won't drain. Highly recommended. I take 1 star off because when I received the TomTom HRM from the seller, the sensor was already installed on the strap and the battery was only at 50% (Runtastic app showed the heart rate and battery level after connected.)

I was real happy with this when I bought it back in July 2016, but now it stops working before I finish my workout. This slowly started happening and I thought it just needed the battery replaced. But changing the battery several times only helped for a short time. Today I couldn't get it to connect after just replacing battery last week.

Works well with my multi sport tomtom watch but sometimes have difficulty pairing up at work... Strap gets really sweaty on long runs. Overall a good strap and comfortable. If your worries about overall fit, this strap is not for you if have a large chest size as it will not stretch much. I am a very petite athlete.

I received this HRM very quickly from Amazon and it works amazingly! You must wet the sensors before each use in order to activate them. My only wish is that the band strap was a bit larger, as I am a bit overweight and the strap is tight, but thats why I got it! Definitely recommend!

No problems connecting this to my TomTom Spark. Now I can get accurate data of how many calories I'm actually burning during my workouts. The only downside (not for this product) is that using the heart rate monitor drains my TomTom watch pretty quickly to where I'm charging it every day. The perk of being able to monitor my heart rate is more important to me than losing battery life in my watch.

The unit works fine and I would love to utilize it for heart rate data but the strap cuts me, not rubs or even creates a blister, it cuts through my skin and I bleed. I've used it as loose as I can without it falling off and the same result as when it's on tighter. I never had any issues with my previous heart rate monitor strap but this one is only getting 1 more shot. If it doesn't clear up, I'll never use it again.
