apple watch's heart rate monitoring

what can i say about these apple watches, i am user of apple watch since 2017, i have used watch 3, 4 6,7,8, se1, se2, and now watch ultra 2. none of them have ever worked properly, i dont know why apple is selling them on such a high price though their main feature of heart rate monitoring is a mess in all models. sometime they said in past that its an issue in model, i have changed the model, but it persists almost i all of their model even in watch ultra 2 now.

now a new rebuttal from apple is ready and that is a software glitch. the software 26.0.1, the latest of apple. companies updates their software's to remove the glitches and apple update them to introduce new glitches.

there is no reason to buy any of the apple product.
