Don't buy this item. Lids too big for the dishes or dishes are small for the lids that they come with. The biggest problem that causes this item not function is the fact that the lids are too big for the containers. Lids don't fit the dishes and they have minimum of 3/8" gap between the lid and the container. This will defeat the purpose of keeping the food warm. Other problems that I could live with if the dishes and lids would match are that the warmer itself came with many scratches and have some uneven spots mostly around the spot welds. The temper glass has hair line fractures the you can clearly see. Don't expect a quality, well made warmer. Quality indicates, as if, this item was made in a garage or small shop.I received this item today in the afternoon and was a spoiler, so I will return it. It's a bummer.If the seller would send me the right size lids or dishes that match the lids then I keep the merchandise. I will update my review if I hear back from seller.9/8/2021 Second review: Amazon sent me the second set of warmer. I ended up only swap the containers. My initial purchased warmer came with slightly small containers in compare with the lids. I'm keeping the new containers from the second shipment and I'm sending the containers that came with my initial purchase. Old lids fit perfect on new containers. I hope this makes sense and help you. Thanks to Amazon and speedy and great customer service.
