Does anyone know if you can buy alternative wrist straps for panic buttons? My mum recently got hers but the strap that came with it itches her arm so she keeps fiddling with it and moving it a bit up her arm. Also the extra bit of strap flaps about catching on her bracelet and clothes. I think a leathery type strap with buckle like a watch strap would be better for her but don't know if you can get continuous one piece straps that will thread through back of panic button like the exsisting strap does. Has anyone swapped the strap on their persons alarm or know if it can be done?
