Sad when the Gua Sha broke
I had these for over a year and use both the roller (keep it in my fridge) and the Gua Sha stone.  But today while washing the stone in the bathroom sink it slipped out of my hands and dropped maybe an inch and broke right in half.  But the value for the two items was definitely worth the year plus I used it.  Be very careful with washing in soapy water, it gets quite slippery!
