"Great product" star star star star star Really like this have had no issues with heating in microwave i just loosened the lid. My lock and lock containers have started to degrade and conscious that glass is better than micro plastics Great to heat in both microwave and oven without lid
"Excellent Microwave Steamer" star star star star star I bought this to replace older plastic products. This contains safe glass and plastic. The glass is lightweight enough to make lifting easier. The frozen veg that I use it for gets nice and hot in a short time in the microwave. I open the top vent, and you can leave the clips undone and the lid stays on, if you are worried they might buckle, as per one review. Very pleased with Purchase..
"Fundamental flaw.." star star_border star_border star_border star_border The lids on these dishes distort under heat - put a sealed dish in the microwave to heat and after a couple of minutes one or more of the clips will have become unlocked as the lid distorts. Once distorted, it is almost impossible to reseal all the clips until the lid has fully cooled down. support_agent A note from the team We’re very sorry to hear its faulty. if you bought it from one of our stores, then you can simply return it and they will be happy to help you.
