Polar heart rate alternatives

So, super dissapointed with the H10. It never just work, always jumps around and destroys the data.

Never had this issue with other brands, but done everything Polar and other recommendations. It still just lives a life on its own, jumping up and down. Example - today I did 10 minutes warmup at recovery sone (super easy pace) but it placed me in some 4 and 5, then 2, then down to below 1, and then back up to 5 in a minute or so.

It’s no point in using it for even if it corrects itself at 10-15 minutes the data for the workout is not valuable anymore, without a lot of manual work. That is super annoying and makes it worthless

Anyone have experiences with the Verity series? Is it the same as the H10, or does it work? Is it more accurate than just using the watch?
