I grabbed a mi band 10 a few weeks ago because I like fitness tracking info, but don’t like being tracked. I think it was $48, and I have it connected to Gadgetbridge. It’s decent overall; not perfect, but the battery lasts more than a week on a charge, and at $48, it’s well below regret level pricing. Not trying to sell you on one btw, just commenting because my impression of smart watches has been the same as yours.
