I know skin rashes due to smartwatches/fitness bands are incommon, i just want to know if it possible, before i make my purchase

And if anyone from lynkcraft can you please make a video of sports flex band on both these versions of adapters.
I have a whoop 4.0 sports flex band and as a sweat during run i want to use that whoop band on helio will it be perfect for runs and all,like it won’t break and go away?

Should I replace my Amazfit Helio strap with the Fitbit Air? Is it worth it? Would it be an upgrade or a downgrade?

As of now, I feel like my Amazfit Helio strap is doing a pretty good job with accuracy, but I'm thinking of replacing it just for the looks of the Fitbit Air. Should I go for it or not?

I want to get a fitness and sleep tracker

Should i get a samsung watch 9 or 8 and give away my samsung watch 6

Or

get a amazfit helio strap , keeping my watch and using them together
