H10 Heart Rate Monitor Chest Strap - ANT + Bluetooth, Waterproof HR Sensor for Men and Women

I have two wahoo tickrs, both work great then I notice they are off by 15 to 25 bpm. I confirm with phone, watch and pulse ox. Next time they are accurate again. Drove me nuts because it was so intermittent. I had polar for decades so I ordered this one. So glad I did. This paired easily with Bluetooth and Ant. Works perfect everytime. I store disconnected as instructed and changed the battery easily after one year using it seven to ten hours a week every week.

I use the "arm bike" at Planet Fitness, it does not have it's own heart rate sensor, but has a place for heart rate on the screen. Based on instructions on that equipment telling me I need a "chest strap heart rate transmitter" I bought this, put it on, used the app to make sure it was transmitting (you do sometimes have to adjust the strap a little), and went to the gym. Started my workout and THERE WAS MY HEART RATE ON THE SCREEN! Yeah, maybe just use a leg bike that has it's own sensor, but my knees are too bad to hope to get a good workout, so I use the arm bike.

Update 10/22/24. Too funny! After 3 months I got another automated email telling me to do the same things I told them I did to get it to work.Polar was literally and figuratively the first name in heart rate monitoring and they've been reduced and degenerated to this. Pathetic.Update 7/20/24:Before I wrote my last update I'd chatted with their bot which told me to send them an email requestion support. I got an email back from Katerina who I'm sure was an email bot. I sent them an email describing the problem. THEN a few days later they send me a survey email asking to rate their customer service. This company and their product ... Dumpster Fire!Update 7/16/24: That's IT, I'm done! I've bought three of these cursed things because I need the functionality of the Flow app. First one went south after about a year and a half - wouldn't connect. Second one stopped connecting after a year. Third one I bought a month ago. First it started reporting lower than actual heartrate, then it started working OK. Then (as others have reported) I had to take 10 minutes before every workout to reset the blasted thing in order for it to connect. Finally it just stopped pairing altogether. Google "H10 won't connect" and you'll find all kinds of ticked off customers. They've stopped phone and even chat customer support and now offer human support only by email!!? Here's a one of the PO'd customers on Reddit: "Done with this piece of garbage - their response time to my email was more than 2 months"I think they're having coding issues and it doesn't exhibit itself in the same manner for different phones. Maybe their code will not keep up with OS updates on some phones or whatever but something's messed up. I like customers cannot get the flow app to update. Used to be great but useless now. What planet are these people on?I can only think that the positive reviews here were as typical .. people get the product and fire off a review after a day or two. Do Not Buy!!Prior review:Very accurate when it pairs and works but the Einstein programmers at Polar really set up a convoluted pairing/connect method that requires you pair through the flow app and can be stubborn as hell sometimes requiring the sensor to be unpaired and reset. It's aggravating as all get out, and as reported by other users will just flat out fail to pair eventually. I generally have to say a rosary to get the damned thing to pair, then perform the stations of the cross in order for the app to recognize the paired device and continue repeating Hail Marys hoping that the results will be accurate as sometimes the flow app will register up to 20 beats fewer than my actual heart rate. If I get it working then I throw a pinch of salt over my shoulder in the hope that the pairing won't drop. Also as reported by other users, I think Polar know their stuff is messed up but won't own up to it. They used to have phone support but I'm sure they got overrun and now they just do chat support where I get a lot of "I understand your frustration" but no solution. Unfortunately once you get it to work this is the most accurate sensor on the market and I need the functionality of the flow software. So since my first two flat out failed to pair after a year I just had to buy my third one. So plan on it being a once a year throwaway product.And if you're really self-loathing go ahead and try to load the Beat app as well as the Flow app. See if you don't start swearing. When I connect to the Beat app it actually breaks the flow app. And don't you DARE try to use another wearable. If I pair my Galaxy watch.. Fuhgedabahdit! I'll be trying to reconnect for the next half hour. So before you buy this thing read the other reviews like the one where the guy has to a lot 10 minutes in advance of his workouts because he has to repair it to his iPhone every time.....If Polar had any integrity they would post these issues and at least indicate that they're working on them on their website instead of just posting we did another update and it fixed some issues etc. I can't wait for the wearable technologies to mature so I can bail on this company. This is the most irritating product I own. I might suggest that Polar drug test their CIO and programmers before they hire them.

The device is simple and inexpensive relative to other tech monitoring devices, but as accurate as it gets for a consumer device and the software makes it surprisingly valuable. The Polar app itself does a great job of tracking a multitude of day activities, for me so far, walking, tennis, cycle, ski and treadmill, but so many more activities that can be tracked. Then an app called sleep2 from Nukkuaa to track sleep pretty accurately without needing the more expensive watches with more features than I need. Wearing the device is a little uncomfortable at night, and the Sleep2 subscription is expensive. But for 2-3 months to see the pattern has been great.

I don't understand why more companies don't use the 5ghz whatever protocol on their monitors for connections to gym equipment but this thing is awesome for having it. It measures quickly and pretty accurately and so far the battery has lasted even if I forgot to remove the sensor from the strap. I love that its water proof, I just rise the band off before and after working out and it's good to go.To get the band primed they say run it under some water which is why I rinse before working out. It's more expensive than one of the blue tooth banded hr monitors but with the three connecton bands available for the unit you get more channels to connect. It sends data to the equipment, my phone, and my watch. It rarely loses connection. I wish I got this sooner it was worth the extra cost for the added features. It opens up a whole set of options on gym equipment.
