Hi, My microwave was broken. So: I need a new one. However, I have a little quirk when it comes to buying anything that’s not perishable. I want to avoid making a bad purchase. I’d rather spend more money once than have to buy a new one in two years. Here, I have to be careful not to fall down a rabbit hole. I can spend hours reading reviews. But what do I even want to compare?
