I'm writing this 2 years later actually to only say one thing wrong with it which is over time it develops what I think are maybe micro cracks and these things mostly inside the microvave explode. Like literally in to many pieces. See picture below.I guess for 2 years they have served us well and have gone through hundreds of heat and cool down cycles. Overall very satisfied with the product but just know that eventually they will start to explode or shatter.If you use it exclusively for serving then maybe they will last longer but if it's going through multiple heat and cool down phases, if will eventually get a little dangerous. Just keep that in mind.So far multiple bowl and plates have exploded either inside the microwave or soon after removing it. Though it didn't happen in the first year of use. Only many months later.
