blech! It's nasty! I have my own bowl, plate and silverware here at work where everyone else uses paper plates and bowls and plasticware that all gets thrown away. I suppose it could get smaller but my waste footprint compared to the average population is quite small, thank you very much!
I've had mine a long time and gone through quite a few microwaves and they're doing pretty well. And again - I'm gonna lose that $30 Sigg thermos LONG before I go through 30 ziploc containters!
