I've had the Costco ones and don't think they're as good as ones you would get at a French pastry shop. However, I haven't watched a presentation on these, nor can I figure out from the on-line description, if you have to heat them or bake them completely. The bake time (25-30 minutes) suggests they need to be baked.
