I’ve had this attachment for years and it generally does a good job for what I’ve used it for in the past…juicing soft fruits and vegetables. Today, for the first time, I was running a batch of blackberries for seedless jam. It seemed to be working well until it didn’t…juice was flowing and the seeds/skins were being ejected as usual and then there was a loud pop. I immediately stopped the machine and disassembled the parts. Much to my dismay and horror, I saw that the sieve weld had failed! I will readily admit that the blackberries were the “seediest” fruit I had ever attempted to strain and apparently that is what ruptured the seam. Bottom line…for a company known for making heavy duty, last-a-lifetime appliances, this attachment failed the first time it was asked to perform a job more difficult than juicing a few oranges or summer tomatoes. I’m a life-long KitchenAid user and fan, but in this case, I am more than disappointed!
