No I haven’t do they not irate at all?
Hi,
I've used a variant to hold a Bluetooth bridge in place over a Libre & found them pretty comfortable.
Worth while shopping around though. Variety of designs & colours. Though the principle is the same.
Just search "Libre guardian armband" & they should come up?
One thought has come to mind regarding your skin irritation. Have you recently changed bathing products or deodorant?
Here is an example below on what you are looking for on the armband front. (I have no affiliation with this product or the vendors, but have used them for a couple of years.)
Hope this helps.
