— DontMentionMyNamePlz on Reddit

“Thanks! As far as temps how does that effect it?”
— breakaway333 on Reddit

“Ive seen your original comment. Your fuse is so short, that you can’t accept fact that’s it is issue on your end. When i purchased ultra 2 it also performer software update and it wasn’t nowhere close to 8 hours.”
— Lelu_zel on Reddit

“Sure thing. Keep trying position and tightness. Temps and wrist size change seem to be the biggest issue for me. Congrats on your first ultra :)”

“This. Apparently the heavier Milanese loop tends to lead to more watch movement on the wrist, leading to less accurate measurements”
— lfirmann on Reddit

“Ok. I only ask because that can cause issues with the heart rate monitor. There are quite a few posts in Apple Watch subs about it.”
— Rabble_Runt on Reddit
