"Worthless"
Steam and heat from the food below cause the flimsy covers to fall off, making them entirely worthless.

"MAJOR disappointment-waste of money"
I can't believe anyone found these covers to be effective - makes me wonder if the reviewers are "plants" from Norpro. Like the previous reviewer a few days ago, I think they are worthless. Upon using each of the different sizes, they immediately curled up. This causes them to blow off of the food the majority of the time (from the micro's fan, I'm guessing)and just lay on the turntable. This is due to the gap that now exists when the cover is lying across the container and is curled up instead of lying flat. The whole purpose of these was to safely cover food to prevent splattering within the micro and to help contain the heat - they do NEITHER! WHAT a waste of time and money. I can't believe the positive reviews below. Just doesn't make sense unless the plastic was of a different grade. I'm going to return these.

"NOT APPROPRIATE for MICROWAVE USE!"
Bought this Norpro set of Micro-Covers with high hopes based on the description and reviews. Followed the directions carefully to avoid problems. First use was in heating microwavable oatmeal. What a disaster! The Micro-Cover was way too light and exploded off the amply sized microwave dish. There was oatmeal splattered all over the inside of the microwave.
Second use was on heating some water in a cup using the small Micro-Cover just like it is pictured on the package. No good! The Micro-Cover curled up from the heat and was therefore useless.
I certainly would not recommend this product. The Micro-Covers are way too light for their purpose and explode off or curl up from the microwave heat. I gave it one star cause that's the minimum allowed.


"Convenient idea!"
Simple idea. Replaces limp, wet pieces of waxed paper or plastic wrap. Protects the inside of the microwave from splatters and traps steam for easy cooking.

Cleans in dishwasher.

My only wish is that there was a larger one in the set.

"I love these"
These are excellent! Instead of reaching for a paper towel, I grab one of these (choosing a size that completely covers the top of the item I am microwaving), and then wash it when finished. I did notice that the smooth side should be on top to prevent it from curling up when it gets hot. I really like the fact that you can see through it since I couldn't see through paper towels.
