Only because I needed this Therapik the other day when I was covered in bug bites and I know it works. It transmits heat against the spot and really stops the itch by activating the spot to focus on the heat “attacking” your skin and getting your brain to switch the focus off the itch.
I ended up buying another one. :-/
Aside from that, not many clothing or shoe purchases have been regrets when I decluttered them.
