For me …
Very comfortable, good absorption: backs of upper arms (despite lipoatrophy), abdomen (from ribs down to belt line, and round the back as far as I can go without the pod pressing against a chair back; shares with Dexcom sensor)
Comfortable, but sometimes iffy absorption (mostly because of said atrophy): top and side of upper thighs
Comfortable as far as pod goes but not comfortable when sitting, though good absorption: upper butt
In two years of podding, I’ve had the occasional bleeding when a pod is removed. Not related to any one place in particular. And I bled after the odd injection, too, so it’s no big deal.
