I guess I was expecting too much when I ordered this, but most pie servers I have ever used have been made of a coated metal. This is a very thick piece of plastic. I purchased the Lapis shade with the scalloped top, and I'm honestly not certain if it would be useful for serving cake or pie as the plastic is thick (not at all smooth or ergonomic) and the design looks like it would make a mess of the bottom of a cake.
If you want to use this for its nice design - go for it. If you want something practical - I think you can find many better options for the price.
