Signal Pre-Flare Patch

They worked very welly only problem was when I was wearing them in the day on my arm it would peel back whenever I put my jacket on.

It works but those are hydrogel pads so it's falls of very easily and you can't wear it when sleeping, well I cant but it's a good product

Did not love Signal. It slides right off, does not stick. It isn’t large enough or healing enough to be worth using since you have to hold it in place.
