I got this bowl set & the size down to replace an ancient Copco set from the '90s.  It does not disappoint.  The large capacity on both bowls is perfect for a double batch of muffins or anything you're making lots of.  It is a heavy plastic that feels sturdy when you're mixing and stirring.  Then, you can throw that bad boy in the dishwasher when you're finished cooking!  The rubberized bottom is essential for holding the bowl in place and the handle is wide enough to accommodate large hands.  A+ on this set and the smaller set too!
