I like this, happy with everything but its either eating batteries or the strap is on its way out. I dual record zwift and garmin when running and garmin/ tr when cycling. its okay for the first hour but then starts dropping off. Fresh batteries doesnt seem to cure the problem. all firmware up to date thoughts or experiences? ---

Mine failed - as did the replacement. Wahoo Tickr 2 has been flawless so far. ---

After 1 year mine suddenly started to drop frequently …then i realized the the strap had some tears that when i started to sweat a lot signal went nuts and started to drop. Bought a generic strap and problem was solved. ---

I’m going on 2.5yrs with my H10 and no real issues to speak of, and very few battery changes too. I’ve been really happy with it. ---

Do you detach the pod from the strap when not in use? ---

Have to say, I never detach mine at all. Use it every single day for a HRV reading and most days for a bike ride ---

Mine eats batteries nonstop. I will probably upgrade to a dual reporting unit like the tickr when the H10 kills its current battery. ---

Battery lasts 400 hours of use. So for me, about 6 months. ---

I do not have it a whole year already, I think about 9 months now. Always detach pod from strap. Have replaced batteries two times already. But, I ride about 12-15k a year, and I also wear it when going out for recovery walks. TICKR same amount of battery replacements. Have been washing the strap every week. So far, so good. fingers crossed… ---

I’ve been impressed with the performance of the Polar H10, but I find that after about 8 months of use (6 days a week) I always tend to get start getting erratic readings (more noticeable when running). Even after a battery change I start to see these kind of readings (this was a consistent effort on a flat(ish) run): ![image](https://global.discourse-cdn.com/trainerroad/original/3X/b/e/beb8498cd6d564769d9949d5c44db706b38e5ecd.png) After replacing just the [strap part](https://www.amazon.co.uk/gp/product/B06X16339Q/?tag=raineoad-21) of the HRM it starts working perfectly again for about another 8 months. It’s starting to get pricey, so I’ve just bought a Tickr to see if that lasts any longer. ---

thats what i was thinking 30 quid for a strap and your buying the device again every 18 months, i have a tickr x as well however its just not as comfortable. i have an OH1 ( i use the OH1 for swimming and the H10 for the pain cave. the tickr x lives in the office for lunch runs. ---

@marco_alt - I know you’ve had plenty of use with the Polar H10 - have you also seen problems with erratic readings starting after less than a year of use? ---

Hi! I have H7 that I used for years without problems but my H10 are all relatively new, so at this stage I haven’t experienced issues. I find that the lack of screws makes it more durable than other sensors (for example some Garmin straps), but there might be other issues. Could also be bad luck 🙂 despite quality control and all, there’s always variability between sensors ---

Adding to this… my H10 has (in the last month) started eating batteries. Not particularly happy about it. I switched from my Wahoo sensor as apparently the Polar is more accurate for HRV, but I can’t be dealing with replacing the battery every other week. Super tedious. (and no, I’m not leaving it connected to the strap) ---

3 years with mine, and I have been through some batteries and a couple straps because I washed them in the washing machine (oops). I always recommend it. Great HRM. [Next page](https://www.trainerroad.com/forum/t/polar-h10-longevity/56741.md?page=2)
