The cold seems to be working great so far and it lasts pretty long
Update:  I just put this in the microwave for 60 seconds and it blew up on me.  The Gel is all all over my microwave and leaking everywhere.  No instructions and such is so dangerous.<br /><br />Bought this as a hot/cold Gel pack.  The cold seems to be working great so far and it lasts pretty long.  I have no idea on how to use the hot.  Microwave?  How long?  Will it leak or blow up in my face?
