This is great and don't know why we haven't had one sooner!  No more microwave mess and no more being wasteful with plastic wrap or paper towels to keep microwave splatter to a minimum.  We simply keep it in the microwave and use it all the time.  Plus works great to heat up two dishes at once!!  Great for left-over nights!
