I'm a personal trainer and nutrition coach and  I was given this Black and decker FP1700B for my business. While at a client's home using for the first time to make almond butter. As it says can be used to make nut butters. While in the midst of preparing the almond butter(blanched almonds might I add) the item started to smoke and the center stem has melted and warped the bowl all while in front of my 
client.  Now my client has half buttered almonds with plastic shards that can't be used. Almonds aren't cheap. I'm so embarrassed and highly disappointed in this product. Prior to this I have only used it for cauliflower and it did well. Again very disappointed!.
